[PATCH 4/4] staging: rtl8192e: Remove checks of pointer to rtllib.. and ScanOpera..

[Philipp Hortmann <philipp.g.hortmann@xxxxxxxxx>]

Function pointers of rtllib_ips_leave and ScanOperationBackupHandler is
set while executing the probe function. Therefore a NULL pointer check is
not required. Remove checks as it is dead code.
