wifi: mwifiex: avoid possible NULL skb pointer dereference
[ Upstream commit 35a7a1ce7c7d61664ee54f5239a1f120ab95a87e ]
In 'mwifiex_handle_uap_rx_forward()', always check the value
returned by 'skb_copy()' to avoid potential NULL pointer
dereference in 'mwifiex_uap_queue_bridged_pkt()', and drop
original skb in case of copying failure.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 838e4f449297 ("mwifiex: improve uAP RX handling")
