Revert "scsi: ufs: try read capacity (10) first"
This reverts commit 7d76a33cac7040f3e05c1a49fc312e53dc3b2f1c.
Read capacity (16) is used, in addition to reading capacity, for
reading unmap command parameters. In UFS spec since v2.0 read
capacity (16) command is mandatory for embedded devices.
If read capacity (16) is not supported by the device then it simply
rejects the scsi command with ILLEGAL_REQUEST in sense key. The sd
driver then retries with read capacity (10), thus keeping backward
compatibility.
