drivers/char/pcmcia/ipwireless/hardware.c fix resource leak
commit 43f77e91eadbc290eb76a08110a039c809dde6c9 upstream
Coverity CID: 2172 RESOURCE_LEAK
When pool_allocate() tries to enlarge a packet, if it can not allocate enough
memory, it returns NULL without first freeing the old packet.
This patch just frees the packet first.
