mwifiex: fix crash during simultaneous scan and connect

If 'iw connect' command is fired when driver is already busy in
serving 'iw scan' command, ssid specific scan operation for connect
is skipped. In this case cmd wait queue handler gets called with no
command in queue (i.e. adapter->cmd_queued = NULL).

This patch adds a NULL check in mwifiex_wait_queue_complete()
routine to fix crash observed during simultaneous scan and assoc
operations.

net: fsl: fec: fix build for mx23-only kernel

If one only selects mx23-based boards, compile fails:

drivers/net/ethernet/freescale/fec.c:410:2: error: 'FEC_HASH_TABLE_HIGH' undeclared (first use in this function)
drivers/net/ethernet/freescale/fec.c:411:2: error: 'FEC_HASH_TABLE_LOW' undeclared (first use in this function)

This is because fec.h uses CONFIG_SOC_IMX28 to determine the register
layout of the core which makes sense since the MX23 does not have a fec.
However, Kconfig uses the broader ARCH_MXS symbol and this way even
makes the fec-driver default for MX23. Adapt Kconfig to use the more
precise SOC_IMX28 as well.
