wlan: replace non-standard "offset" macro in wlan_hdd_cfg.h

wlan_hdd_cfg.h currently defines a "FIELD_OFFSET()" macro, the usage
of which produces compiler warnings when the prima driver is compiled
on certain architectures.  Replace this macro with the Linux standard
"offsetof()" macro to prevent these warnings.
