[PATCH] port-serial: fix command context completion when clearing command queue

[Ben Chan]

This patch removes an extra invocation of g_simple_async_result_complete
on the result associated with each command context in the command queue
when mm_port_serial_close clears the queue. It also changes the code to
complete the results in idle, which avoids a nested invocation of
mm_port_serial_close. That could happen if the completion of the result
calls mm_port_serial_close again (e.g. via at_command_context_free,
at_sequence_context_free in mm-base-modem-at.c). The nested invocation
of mm_port_serial_close could create undesirable effects (e.g. the
assertion on open_count > 0 fails in case of a forced close).
