Subject: [PATCH] uqmi: evaluate pin-status output in qmi_setup function

Load the json output from uqmi --get-pin-status command and evaluate the
"pin1_status" value.

The following uqmi "pin1_status" values are evaluated:

- disabled
  Do not verify PIN because SIM verification is disabled on this SIM

- blocked
  Stop qmi_setup because SIM is locked and a PUK is required

- not_verified
  SIM is not yet verified. Do a uqmi --verify-pin1 command if a SIM is
  specified

- verified:
  Do not verify the PIN because this was already done before
