wifi: brcmfmac: Set DMA direction for msgbuf packet IDs

brcmf_msgbuf_init_pktids() takes the DMA direction from its callers,
but never stores it in the packet ID state.  Since the state is zeroed,
pktids->direction remains DMA_BIDIRECTIONAL for both the TX and RX
packet ID pools.

All msgbuf packet ID map and unmap paths use pktids->direction.  As a
result, TX buffers requested with DMA_TO_DEVICE and RX buffers requested
with DMA_FROM_DEVICE are mapped and unmapped as DMA_BIDIRECTIONAL
instead.

Store the caller-provided direction when initializing the packet ID
state.
