Revert "modemmanager: add more retries for port AT probing" 

Adding more retries to the port AT probing has an impact in modems not
using serial drivers (for example using qmi, mbim). It takes longer for
MM to detect those modems and then user space gives up waiting for the
modems to be available.

This reverts commit 682d77e414.

Subject: [PATCH] port-probe: add more retries for port AT probing
Launching the MM on target's boot fails to detect the XBee cellular
because this needs more time to complete the initialization. So add some
more retries for the AT port probing to allow the XBee cellular to be
detected.
Upstream-Status: Inappropriate [embedded specific (Xbee cellular)]
