Possible memory leak in function (r8712_setrttbl_cmd) not freeing pointer (ph2c) on error path

Bug Report Filed: https://bugzilla.kernel.org/show_bug.cgi?id=88881
Linux Version [3.17-rc1]
Configuration: Default configuration for x86

In function (r8712_setrttbl_cmd) file (drivers/staging/rtl8712/rtl871x_cmd.c):

Function (r8712_setrttbl_cmd) allocates the variable (ph2c) at line
732 and passes it as a parameter to function (r8712_enqueue_cmd) at
line 743. Function (r8712_setrttbl_cmd) returns (_SUCCESS) result
regardless of the result of the called function (r8712_enqueue_cmd)
which may return (_FAIL) at line 176. This failure causing the
allocated object not to be queued and hence not freed later. Thus,
causing a possible memory leak not freeing the (ph2c) pointer upon
(_FAIL) return of function (r8712_enqueue_cmd).
