Subject: [PATCH V2] ath10k: don't fail if IRAM write fails

After reboot with kernel & firmware updates I found `failed to copy
target iram contents:` in dmesg and missing wlan interfaces for both
of my QCA9984 compex cards. Rolling back kernel/firmware didn't fixed
it, so while I have no idea what's actually happening, I don't see why
we should fail in this case, looks like some optional firmware ability
that could be skipped.

Also with additional logging there is
```
[ 6.839858] ath10k_pci 0000:04:00.0: No hardware memory
[ 6.841205] ath10k_pci 0000:04:00.0: failed to copy target iram contents: -12
[ 6.873578] ath10k_pci 0000:07:00.0: No hardware memory
[ 6.875052] ath10k_pci 0000:07:00.0: failed to copy target iram contents: -12
```
so exact branch could be seen.

Of course I forgot to sing off, since I don't use it by default because I
hate my real name and kernel requires it

Thanks for working on this! And sorry for the slow response. I've been
unexpectedly very busy lately, but I plan to test out this patch next
week.

Sorry again for the slow response time.

I got around to testing this today on my hardware. I tested with a
vanilla 5.13.8 kernel, and then the same kernel with this patch
applied. Long story short, the patch does indeed seem to at least work
around the issue I was seeing in [1]. With this patch applied, I still
get the same "failed to copy target iram contents" error, but the
interface comes up and seems to be functional regardless.

So, for what it's worth (granted I am no wireless expert!), you can take:

Tested-by: Axel Rasmussen <[email protected]>

(This issue has nothing to do with my full time job, but I'm meant to
use my @google.com address for any open source contributions, which I
believe applies to commit messages too.)
