staging: r8188eu: Calling rtw_get_stainfo() with a NULL sta_addr will return NULL
commit
9452bf560273e4de2395ffdd79024debfb0c1290 upstream.
This makes the follow-on check for psta != NULL pointless and makes
the whole exercise rather pointless. This is another case of why
blindly zero-initializing variables when they are declared is bad.
