[PATCH 1/3] staging: r8188eu: Remove unused static inline functions in rtw_recv.h

[Nathan Chancellor <nathan@kernel.org>]

After commit 987219ad34a6 ("staging: r8188eu: remove lines from Makefile
that silence build warnings"), clang warns several times:

In file included from
drivers/staging/r8188eu/os_dep/../include/drv_types.h:22:
drivers/staging/r8188eu/os_dep/../include/rtw_recv.h:395:9: warning:

        return buf_desc;
               ^~~~~~~~

        unsigned char *buf_desc;
                               ^
                                = NULL
drivers/staging/r8188eu/os_dep/../include/rtw_recv.h:412:52: warning:

        precv_frame = rxmem_to_recvframe((unsigned char *)buf_star);
                                                          ^~~~~~~~

        u8 *buf_star;
                    ^
                     = NULL
2 warnings generated.

The functions that these warnings come from are not used or are called
from functions that are not used so just remove them to remove the
warnings.
