scsi: libsas: fix race of setting phy linkrate with lldd

hulk inclusion
category: bugfix
bugzilla: NA
CVE: NA

---------------------------

The linkrate for direct phys is set by lldd. We should not set it
because the phy event is async with the lldd events.

After commit 24fa9796a5b0 ("{topost} scsi: libsas: re-init the
negotiated_linkrate when phy down v2") has already set this in
sas_phy_disconnected() and this function is directly called by the lldd,
we do not need this in sas_deform_port().
