ntfs: add bound checking to ntfs_external_attr_find

Add bound validation in ntfs_external_attr_find to
prevent out-of-bounds memory accesses. This ensures
that the attribute record's length, name offset, and
both resident and non-resident value offsets strictly
fall within the safe boundaries of the MFT record.
