Revert "scsi: ufs: fix failure to read the string descriptor"

This reverts commit b0a12b45.

Content added by the commit that is reverted is already presented
into msm-4.9 as part of change [1], where the delta was taken
from msm-4.4 change [2]. Note that [2] is created on a slightly
extended code as compared with the reverted change done with
changes [3] and [4].

In summary, change [2] is upstreamed as b0a12b45.

Motivation to revert the change is because it is causing merge
conflicts on importing android-4.9.107 (42a730ad) into msm-4.9,
hence let's remove it before the merge.

[1] cce6fbcb ufs: snapshot of UFS driver
[2] 878c98c scsi: ufs: fix failure to read the string descriptor
[3] a7da3b2 scsi: ufs: add descriptor read support
[4] cb6bbbd scsi: ufs: add index details to query error messages
