Subject: [PATCH] staging: wilc1000: remove redundant masking of pkt_offset

From: Colin Ian King <colin.king@...onical.com>

The masking update of pkg_offset is redundant as the updated
value is never read and pkg_offset is re-assigned on the next
iteration of the loop.  Clean this up by removing the redundant
assignment.

Addresses-Coverity: ("Unused value")
