scsi: ufs: core: Include UTP error in INT_FATAL_ERRORS
[ Upstream commit 558ae4579810fa0fef011944230c65a6f3087f85 ]
When a UTP error occurs in isolation, UFS is not currently recoverable.
This is because the UTP error is not considered fatal in the error
handling code, leading to either an I/O timeout or an OCS error.
Add the UTP error flag to INT_FATAL_ERRORS so the controller will be
reset in this situation.
