[PATCH] staging: rtl8712: Fix return type for implementation

[GUO Zihua]

Since Linux now supports CFI, it will be a good idea to fix mismatched
return type for implementation of hooks. Otherwise this might get
cought out by CFI and cause a panic.

Use enums from netdev_tx_t as return value instead, then change return
type to netdev_tx_t.
