extmod/network_ninaw10: Switch to using soft-timer for polling. 

This patch simplifies the connection and sockets polling code, by switching
to a soft-timer to schedule polling code, and by using one node for
scheduling.  This also fixes any issues that could result from using a heap
allocated machine_timer, and includes better handling of the sockets poll
list.
