[PATCH] staging: wilc1000: return -ENOMEM when kmalloc failed

[Luis de Bethencourt <luisbg@xxxxxxxxxxxxxxx>]

The driver is using -1 instead of the -ENOMEM defined macro to specify that
a buffer allocation failed.

Fixes smatch warning and similars:
drivers/staging/wilc1000/host_interface.c:1782 Handle_Key() warn:
returning -1 instead of -ENOMEM is sloppy
