nfit: fix unchecked dereference in acpi_nfit_ctl
Incremental patch to fix the unchecked dereference in acpi_nfit_ctl.
Reported by Dan Carpenter:
"acpi/nfit: fix cmd_rc for acpi_nfit_ctl to
always return a value" from Jun 28, 2018, leads to the following
Smatch complaint:
drivers/acpi/nfit/core.c:578 acpi_nfit_ctl()
warn: variable dereferenced before check 'cmd_rc' (see line 411)
drivers/acpi/nfit/core.c
410
411 *cmd_rc = -EINVAL;
^^^^^^^^^^^^^^^^^^
Patch adds unchecked dereference.
