[PATCH AUTOSEL for 4.9 170/219] mwifiex: Fix invalid port issue

From: Ganapathi Bhat <gbhat@marvell.com>

[ Upstream commit ecd7eb7c2bcf99f6c23d68ad56ce15949da848a1 ]

We have to use start port, for TX/RX of single packet,
instead of current aggregating port. This will fix SDIO
CMD53(TX/RX) returning -ETIMEDOUT and halting the data path.

Fixes: 0cb52aac4d19 ("mwifiex: do not set multiport flag for tx/rx single packet")
