staging: vt665x: fix alignment constraints
multiple structures contains a ieee80211_rts structure, which is required to
have at least two byte alignment, but are annotated with a __packed attribute
to force single-byte alignment:
staging/vt6656/rxtx.h:98:1: warning: alignment 1 of 'struct vnt_rts_g' is less than 2 [-Wpacked-not-aligned]
staging/vt6656/rxtx.h:106:1: warning: alignment 1 of 'struct vnt_rts_ab' is less than 2 [-Wpacked-not-aligned]
staging/vt6656/rxtx.h:116:1: warning: alignment 1 of 'struct vnt_cts' is less than 2 [-Wpacked-not-aligned]
I see no reason why the structure itself would be misaligned, and all members
have at least two-byte alignment within the structure, so use the same
constraint on the sturcture itself.
