[PATCH] ufs: core: fix WB resize use wrong offset

[Huan Tang]

'Commit 500d4b742e0c ("scsi: ufs: core: Add WB buffer resize support")'
incorrectly reads the value of offset
"DEVICE_DESC_PARAM_EXT_UFS_FEATURE_SUP" to determine whether WB resize
is supported.

Fix the issue by read the value of "DEVICE_DESC_PARAM_EXT_WB_SUP"
to determine whether the device supports WB resize.
