scsi: ufs: core: Fix WB resize using wrong offset

Browse Source 
Commit 500d4b742e ("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 reading the value of DEVICE_DESC_PARAM_EXT_WB_SUP to
determine whether the device supports WB resize.
