[SCSI] ses: add support for enclosure component hot removal

Right at the moment, hot removal of a device within an enclosure does
nothing (because the intf_remove only copes with enclosure removal not
with component removal). Fix this by adding a function to remove the
component.  Also needed to fix the prototype of
enclosure_remove_device, since we know the device we've removed but
not the internal component number
