prism54: remove questionable down_interruptible usage
Reviewing the semaphore usage I noticed these down_interruptible calls. Most
of these aren't returning anything, so a caller can't tell if the operation
completed or not. prism54_wpa_bss_ie_get() returns zero, but it's treated as
the function failing which doesn't seem correct.
