[PATCH] staging: wlan-ng: Fix endianness warnings

[PATCH] staging: wlan-ng: Fix endianness warnings

[alfonsolimaastor]

From: Alfonso Lima Astor <alfonsolimaastor@gmail.com>

These variables were set to u16 and u32 although they always hold a little
endian value.

This patch fixes multiple sparse warnings like:
drivers/staging/wlan-ng/prism2sta.c:375:46: warning: cast to restricted __le16
