scsi: sd: Clear sdkp->protection_type if disk is reformatted without PI
commit 465f4edaecc6c37f81349233e84d46246bcac11a upstream.
If an attached disk with protection information enabled is reformatted
to Type 0 the revalidation code does not clear the original protection
type and subsequent accesses will keep setting RDPROTECT/WRPROTECT.
Set the protection type to 0 if the disk reports PROT_EN=0 in READ
CAPACITY(16).
