mwifiex: don't leak stashed beacon buffer on reset

When removing or resetting an mwifiex device, we don't remember to free
the saved beacon buffer. Use the (somewhat misleadingly-named)
mwifiex_free_priv() helper to handle this.

Noticed by kmemleak during tests:

echo 1 > /sys/bus/pci/devices/.../reset

unreferenced object 0xffffffc09d034a00 (size 256):
