[media] m88rs2000: initialize status to zero 

status is not initialized so it can contain garbage. The
check for status containing the FE_HAS_LOCK bit may randomly pass
or fail if the read of register 0x8c fails to set status after 25
read attempts.  Fix this by initializing status to 0.

Issue found with CoverityScan, CID#986738
