scsi: Revert "scsi: ufs: core: Probe for EXT_IID support"

This reverts commit 6e1d850acff9477ae4c18a73c19ef52841ac2010.

Although added a while ago, to date no one make use of ext_iid,
specifically incorporates it in the upiu header.  Therefore, remove it as
it is currently unused and not serving any purpose.
