wifi: brcmfmac: unmap dma buffer in brcmf_msgbuf_alloc_pktid()
After the DMA buffer is mapped to a physical address, address is stored
in pktids in brcmf_msgbuf_alloc_pktid(). Then, pktids is parsed in
brcmf_msgbuf_get_pktid()/brcmf_msgbuf_release_array() to obtain physaddr
and later unmap the DMA buffer. But when count is always equal to
pktids->array_size, physaddr isn't stored in pktids and the DMA buffer
will not be unmapped anyway.
Fixes: 9a1bb60250d2 ("brcmfmac: Adding msgbuf protocol.")
