[PATCH v2 06/11] staging: rtl8192e: Remove unused variables num_proc.., recei.. and rxov..

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

num_process_phyinfo, received_bwtype and rxoverflow are initialized and
increased but never read. Remove dead code. As a result prxsc is unused
which in result makes rxsc_sgien_exflg unused. Remove prxsc and
rxsc_sgien_exflg as well.
