[MM] [PATCH] iface-modem: increase number of trials for PIN check from 3 to 6

[Ben Chan <benchan chromium org>]

In practice, it may take longer time for a SIM to become ready when the
modem interface tries to use AT+CPIN? to determine if the SIM is
PIN-locked. This patch increases the number of trials for PIN check to
address the issue.
