qcacmn: Fix double unmap issue for rx frag packets
Currently as part of rx frag packets handling, nbuf is unmapped,
but the corresponding rx desc unmapped bit is not set. The fragment
is stored until all the frags are received. Only after all the frags
are received defrag packet is reinjected back to reo. While in between
if driver is unloaded, as part of unload rx desc buffer pool is freed.
During buffer free corresponding rx desc unmapped bit is checked and
if the bit is not set buffer is unampped and then freed. This leads
of double unmap in case of the stored frag list buffers. As part of
this change set the unmapped bit during nbuf unmap.
