    rx: Convert rx_FreeSQEList to rx_freeServerQueue
    
    Currently, rx_serverQueueEntry structs are placed on the
    rx_FreeSQEList linked list instead of being freed directly, but
    managing this list is done a bit oddly. The first field in struct
    rx_FreeSQEList is an opr_queue, but we don't use the opr_queue_*
    macros to manage the list. Instead, we just assume the first field in
    a struct rx_serverQueueEntry is a pointer that we can use to link
    entries together. This is currently true and works, but it's an odd
    way of maintaining such a list, and of course would break if we ever
    moved the fields around in struct rx_serverQueueEntry.
    
    Make this code more closely follow the normal way of managing
    opr_queue lists, by using opr_queue_* macros, and changing
    rx_FreeSQEList to be an opr_queue itself. Change the name to
    rx_freeServerQueue to ensure all callers are changed, and to match the
    naming convention for the other linked lists for rx_serverQueueEntry
    structs. Also move rx_freeServerQueue and its associated lock
    freeSQEList_lock to be declared static inside rx.c, since neither are
    referenced outside of rx.c.
    
    The general idea for this commit suggested by kaduk@mit.edu.
