staging: rtl8723bs: Fix trailing semicolon

The trailing semicolon is an empty statement that does no operation. Removing it since it doesn't do anything.

Hi all,

Testing the waters with this cleanup patch. If it is OK to send these there are two very similar ones, plus more in general. Happy to send them.

I have a C.H.I.P. board, which is why this driver is interesting for me to play with.

Thanks for the review so far,
Luis
