Subject: [PATCH v2 3/3] staging: r8188eu: remove rtw_hal_c2h_handler function

Remove rtw_hal_c2h_handler function from hal/hal_intf.c, as well as its
declaration in include/hal_intf.h, and remove its one remaining caller
within core/rtw_cmd.c.

This function was a wrapper function, then simplified to always return
_FAIL. Since it has no further use, remove it, as part of ongoing
efforts to simplify and remove the HAL layer of the driver.
