[PATCH][next] staging: wilc1000: remove redundant assignment to variable result

[Colin King]

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

The variable result is being initialized with a value that
is never read and is being re-assigned later on. The assignment
is redundant and hence can be removed.

Addresses-Coverity: ("Unused value")
