Subject: [PATCH AUTOSEL 4.14 115/371] staging: rtlwifi: Use proper enum for return in halmac_parse_psd_data_88xx

From: Nathan Chancellor <natechancellor@...il.com>

[ Upstream commit e8edc32d70a4e09160835792eb5d1af71a0eec14 ]

Clang warns:

drivers/staging/rtlwifi/halmac/halmac_88xx/halmac_func_88xx.c:2472:11:
warning: implicit conversion from enumeration type 'enum
halmac_cmd_process_status' to different enumeration type 'enum
halmac_ret_status' [-Wenum-conversion]
                        return HALMAC_CMD_PROCESS_ERROR;
                        ~~~~~~ ^~~~~~~~~~~~~~~~~~~~~~~~
1 warning generated.

Fix this by using the proper enum for allocation failures,
HALMAC_RET_MALLOC_FAIL, which is used in the rest of this file.
