staging: vt6656: WCTLbIsDuplicate fix PSCacheEntry base types and warnings

Fix wFmSequence and wFrameCtl to __le16

Don't restrict to u8, if packet is a duplicate both bytes of __le16 will be
the same.

Fixes warnings
wctl.c:66:9: warning: restricted __le16 degrades to integer
wctl.c:71:56: warning: restricted __le16 degrades to integer
wctl.c:73:49: warning: cast from restricted __le16
wctl.c:83:30: warning: incorrect type in assignment (different base types)
wctl.c:83:30:    expected unsigned short [unsigned] [usertype] wFmSequence
wctl.c:83:30:    got restricted __le16 [usertype] seq_ctrl
wctl.c:85:28: warning: incorrect type in assignment (different base types)
wctl.c:85:28:    expected unsigned short [unsigned] [usertype] wFrameCtl
wctl.c:85:28:    got restricted __le16 [usertype] frame_control
