This patch increases the response timeout for the probe AT commands.
We've been noticing some modems taking upto 6 seconds to respond to the
initial probe command after a reset which results in modem-manager timing
out and sending a second probe command. The modem sends a response
after about 6 seconds for the initial probe command which modem-manager
treats as response to second probe command and this results in the
modem-manager and modem going out of sync because the modem's second probe
response is treated as response to the next initialization AT command by
modem-manager.
