Subject: [PATCH v2] staging: rtl8723bs: remove unnecessary goto jumps

The next instruction for both 'goto exit' jump statements is to
execute the exit jump instructions regardless. We can safely
remove all jump statements from __init rtw_drv_entry()

Oops! My bad... again :(

I removed the line to take away one of the many checkpatch.pl messages.

I'll be sending v3 here momentarily with an updated commit message
