ocfs2: validate inline xattr header before ibody remove
[BUG]
A corrupt inline xattr header can make ocfs2_xattr_ibody_remove() pass an
unchecked header into ocfs2_remove_value_outside() during inode xattr
teardown.
[CAUSE]
ocfs2_xattr_ibody_remove() still rebuilt the ibody xattr header directly
from di->i_xattr_inline_size and then handed it to code that iterates
xh_count and entry geometry.
[FIX]
Validate the inline xattr header with the shared helper before handing it
to the outside-value removal path, and propagate -EFSCORRUPTED on bad
metadata instead of traversing the unchecked header.
