staging: wfx: drop protection for asynchronous join during scan 

In former code (before the inclusion of the driver in mainline kernel),
hif_join() could run asynchronously. When a join request was in
progress, it was forbidden to launch hif_scan().

Now, hif_join() is always run synchronously. There is no more reasons to
keep a protection against this case.
