Subject: [PATCH v4 5/5] staging: r8188eu: incorrect type in assignment

Fix sparse warning:
> rtw_br_ext.c:516:57: warning: incorrect type in assignment
    (different base types)
> rtw_br_ext.c:516:57:    expected unsigned short
> rtw_br_ext.c:516:57:    got restricted __be16 [usertype]

*pMagic holds __be16 change it's type to __be16

Incorrectly removed htons() to satisfy sparse warning. Instead make
pMagic use the appropriate bid endian type
