Summary
scsi: ufs: core: Remove SCSI host only if added
Details

In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: core: Remove SCSI host only if added

If host tries to remove ufshcd driver from a UFS device it would cause a kernel panic if ufshcdasyncscan fails during ufshcdprobehba before adding a SCSI host with scsiaddhost and MCQ is enabled since SCSI host has been defered after MCQ configuration introduced by commit 0cab4023ec7b ("scsi: ufs: core: Defer adding host to SCSI if MCQ is supported").

To guarantee that SCSI host is removed only if it has been added, set the scsihostadded flag to true after adding a SCSI host and check whether it is set or not before removing it.
