a650d86bcaf5 wifi: rtw89: use int type to store negative error codes
With below changes because of smatch warning:
rtw89/mac.c:1197 rtw89_mac_hfc_init() warn: missing error code? 'ret'
Changes:
The change of 'int' type seemingly give smatch a hint to treat 'ret'
as error code, detecting if we miss to assign proper error code.
