cmd: pinmux: update result of do_status

Browse source 
Update the result of do_status and always returns a CMD_RET_ value
(-ENOSYS was a possible result of show_pinmux).

This patch also adds pincontrol name in error messages (dev->name)
and treats correctly the status sub command when pin-controller device is
not selected.
