    Issue : Switch swap doesn't work when device missing delay is enabled.
    
    (1) add support to individually add and remove phys to and from
    existing ports. This replaces the routine
    _transport_delete_duplicate_port.
    (2) _scsih_sas_host_refresh - was modified to change the link rate
    from zero to 1.5 GB rate when the firmware reports there is an
    attached device with zero link.
    (3) add new function mpt2sas_device_remove, this is wrapper function
    deletes some redundant code through out driver by combining into one
    subrountine
    (4) two subroutines were modified so the sas_device, raid_device, and
    port lists are traversed once when objects are deleted from the list.
    Previously it was looping back each time an object was deleted from the
    list.
