Defect Description:
	PHKL_30582:
	( SR:8606341565 CR:JAGaf02474 )
	Earlier in the mount process, an inode with typed extents
	fails validation. The inode is marked bad but the buffer
	used to read the inode is not properly released.
	The mount process is stuck waiting for this buffer
	to be released.

	Resolution:
	Code changes were done to release the buffer
	when the validation routine returns an error.

Enhancement:
	No
