wifi: plfxlc: fix potential memory leak in __lf_x_usb_enable_rx()

Browse Source 
[ Upstream commit 895b3b06efc285c1245242e9638b9ae251dc13ec ]

urbs does not be freed in exception paths in __lf_x_usb_enable_rx().
That will trigger memory leak. To fix it, add kfree() for urbs within
"error" label. Compile tested only.
