[PATCH v3 3/5] staging: r8188eu: incorrect type in csum_ipv6_magic

[Aakash Hemadri <aakashhemadri123@gmail.com>]

Fix sparse warning:
> rtw_br_ext.c:771:84:    got restricted __be16 [usertype] payload_len
> rtw_br_ext.c:773:110: warning: incorrect type in argument 2
    (different base types)
> rtw_br_ext.c:773:110:    expected int len
> rtw_br_ext.c:773:110:    got restricted __be16 [usertype] payload_len

csum_ipv6_magic and csum_partial expect int len not __be16, use
be16_to_cpu()
