wlan: Add helper function hdd_priv_get_data for "compat" support

Compat handling is required for some ioctl handlers when used in
32U/64K environment.
Adding a common function hdd_priv_get_data() for compat handling
so that when the driver is part of 64-bit kernel, handlers can
use it to work with 32-bit userspace applications
