Rename identifer 'foo' to 'rc' Suggested-by Alison Schofield in functions
skb_p80211_to_ether() and skb_ether_to_p80211().
Fix indentation necessitated by above rename Suggested-by Dan Carpenter
and Philipp Hortmann.
This change adds intuitive meaning to the idenfier, adhering to best
practices and coding style.
Also, driver has been included in the subject Suggested-by Philipp Hortmann.

Changes since v2:
- Fix wrong indentation introduced in v1
- Correct subject to include driver from v1
Changes since v1:
- Rename identifier 'foo' to 'decrypt_check'

Hi Felix,
Thanks for sending this v3 as a new patch. Now, I'm going to ask
you to create a v4 to straighten out a bit more of the patch
format.
The commit message below includes some revision history that only
belongs below the '---', Your commit message will be with this
patch when it is committed, and the changelog will fall away.
The changelog benefits reviewers today, and it also is always
retrievable in Lore for folks curious about the patches journey.
So, I'll make some edits directly below indicating what I think
v4 should look like.
Caveat 1: I didn't test the patch. I expect it applies, compiles,
and passes checkpatch. Double check that all on v4.
Caveat 2: I don't know if GregKH is going to accept this trivial
patch. That's OK. By the time we get though v4 you will have
applied a bunch of patching practices that you can take forward
to your next patches.

Replace above with:
Rename identifier 'foo' to 'rc' in skb_p80211_to_ether() and
skb_ether_to_p80211() to match the common kernel coding style.
(Try to get the spell checker running with checkpatch to catch things
like the misspelled 'identifer' above.)

(The names in parens is optional. Folks often do it to make
it easier for reviewers to find what they last commented, and
also it is a bit of a nod, appreciating your reviewers)
