ntfs: add bound checking to ntfs_attr_find

Add bound validations in ntfs_attr_find to ensure
attribute value offsets and lengths are safe to
access. It verifies that resident attributes meet
type-specific minimum length requirements and
check the mapping_pairs_offset boundaries for
non-resident attributes.
