Subject: [PATCH] brcmfmac: avoid duplicated suspend/resume operation

The lines above are not needed.

WiFi chip has 2 SDIO functions, and PM core will trigger
twice suspend/resume operations for one WiFi chip to do
the same things. This patch avoid this case.

Inner parens not needed on this line.

Well, actually this patch should not affect those line as it would reintroduce a recently fixed issue.
