base-modem: synchronize initialize/enable/disable/sync operations
Each of these now holds an exclusive lock, so all these operations are
synchronized.
This logic can be tested by queing different enable/disable operations
one after the other, e.g.:
mmcli -m a -d & --> Disable 1
sleep 0.2
mmcli -m a -e & --> Enable 1
sleep 0.2
mmcli -m a -e & --> Enable 2
sleep 0.2
mmcli -m a -d & --> Disable 2
sleep 0.2
mmcli -m a -e & --> Enable 3
sleep 0.2
mmcli -m a -d & --> Disable 3
This previous sequence produces MM logs as follows:
