Fix intermittency in ZFS tests that disable SAS phys

tests/sys/cddl/zfs/include/libsas.kshlib
	In disable_sas_disk, wait for the disk to disappear before
	returning.  If it doesn't disappear within 2 seconds, try disabling
	the phy again.  This is necessary because disabling the phy
	sometimes fails if there is a command outstanding at the time.  I
	think the HBA's error recovery code might be resetting the phy in
	that case.  Also, in enable_sas_disk, wait for the disk to reappear.

tests/sys/cddl/zfs/tests/zfsd/zfsd_replace_003_pos.ksh
	Every place that was using (enable|disable)_sas_disk was already
	waiting for the disk to (re|dis)appear, so move that code into a
	common location in libsas.kshlib.  Also remove some superfluous
	rescan_disk calls.
