ANDROID: scsi: ufs: replace fill_prdt with Android vendor hook

Browse Source 
Like was done for the other non-upstream methods in
'struct ufs_hba_variant_ops', replace ->fill_prdt() with an Android
vendor hook.  This is considered to be better because it avoids any
conflicts with upstream changes to 'struct ufs_hba_variant_ops'.

Note that as a side effect of this change, fill_prdt is no longer
allowed to sleep.  That's fine for the only known use of this hook.
