[PATCH 32/61] staging: brcm80211: remove tsf retrieval from wlc_bmac.c

Upon receiving a packet the lowest 32 bits of tsf are filled in
by wlc_bmac in wlc_bmac_recv, but this is not useful as wlc_main
needs to reconstruct 64 bit tsf which is retrieves to recover the
actual tsf value at which packet is received. Therefore tsf
retrieval is removed from wlc_bmac.c.
