Subject: [PATCH 4.20 080/183] scsi: ufs: Fix geometry descriptor size

4.20-stable review patch.  If anyone has any objections, please let me know.

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

[ Upstream commit 9be9db9f78f52ef03ee90063730cb9d730e7032b ]

Albeit we no longer rely on those hard-coded descriptor sizes, we still use
them as our defaults, so better get it right. While adding its sysfs
entries, we forgot to update the geometry descriptor size. It is 0x48
according to UFS2.1, and wasn't changed in UFS3.0.

[mkp: typo]
