commit 8e83e206f4e19566e88d5aec6f58dd4736ae43f8

    sockets.c: Make sock_inc_used overflow check robust.
    
    Before this patch, it was possible that the overflow check might
    miss an overflow event.
    
    e.g. Consider 2 threads, both executing this method. u8_t fd_used is on 
255...
    
    Thread A -> atomically increment fd_used (which is now 0)
    Thread B -> atomically increment fd_used (which is now 1)
    Thread A -> check overflow... sees everything ok
    Thread B -> check overflow... sees everything ok
    
    And the overflow is missed :(
