stdlib: Fixup mbstowcs NULL __dst handling. [BZ #29279]
commit 464d189b9622932a75302290625de84931656ec0 (origin/master, origin/HEAD)

stdlib: Remove attr_write from mbstows if dst is NULL [BZ: 29265]
Incorrectly called `__mbstowcs_chk` in the NULL __dst case which is
incorrect as in the NULL __dst case we are explicitly skipping
the objsize checks.
As well, remove the `__always_inline` attribute which exists in
`__fortify_function`.
