[PATCH 2/2] staging: r8188eu: Fix undersized array in rtw_xmit.c

[Larry Finger <Larry.Finger@lwfinger.net>]

Compiling with -warray-bounds yields the following warning:

drivers/staging/r8188eu/core/rtw_xmit.c: In function ‘rtw_alloc_hwxmits’:
drivers/staging/r8188eu/core/rtw_xmit.c:1493:24: warning: array subscript 4 is outside array bounds of ‘void[64]’ [-Warray-bounds]

  602 |                                 flags, size);
      |

This warning arises because macro HWXMIT_ENTRY is too small.
