mwifiex_bss_ioctl_ibss_channel() which sets the high 16 bits.  This
works on little endian systems but not on big endian ones.  I've changed
mwifiex_drv_change_adhoc_chan() to use a 16 bit variable.  This matches
the other functions in the file.

I considered changing mwifiex_change_adhoc_chan() as well but it turns
out that the function isn't implemented so I just removed the
