staging: wilc1000: check for kmalloc allocation failures
There are three kmalloc allocations that are not null checked which potentially could lead to null pointer dereference issues. Fix this by adding null pointer return checks. Detected by CoverityScan, CID#1466025-27 ("Dereference null return") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
