These patches fix three categories of checkpatch warnings (redundant
braces, redundant else branches after return/break, and constant
placements on tests) in file rtw_mlme_ext.c, which is part of the
rtl8723bs driver. False positives, such as

if (foo) {
	/* TODO: ... */
}

were not altered.

---
v1 -> v2: Removing a redundant else branch left a variable declaration
mixed with code, which was caught by the kernel test bot. Move the
declaration to the beginning of a function.

Oops, apologies for the noise!

I tried to send v2 of the patchset but I had older versions of the
patches in /tmp and since I specified /tmp/*.patch to git send-email
per tutorial, it ended up sending all of the files there. I will send
a v3 ASAP and update the tutorial to prevent others from repeating the
same mistake!
