Commit 11189c1089 "acpi/nfit: Fix command-supported detection" broke
ND_CMD_CALL for bus-level commands. The "func = cmd" assumption is only
valid for:
ND_CMD_ARS_CAP
ND_CMD_ARS_START
ND_CMD_ARS_STATUS
ND_CMD_CLEAR_ERROR
The function number otherwise needs to be pulled from the command
payload for:
NFIT_CMD_TRANSLATE_SPA
NFIT_CMD_ARS_INJECT_SET
NFIT_CMD_ARS_INJECT_CLEAR
NFIT_CMD_ARS_INJECT_GET
Update cmd_to_func() for the bus case and call it in the common path.
