Takashi Yano bc986b7ff6 stdio: Fix bugs in commit 3d94e07c49 
The commit 3d94e07c49 has a few bugs which cause testsuite failure
in libstdc++. This is due to excess orientation check in __srefill_r()
and _ungetc_r(). Further, sscanf() family also calls ssvfscanf() family
with fp->_file == -1. This causes undesired orientation set/check for
sscanf() family. This patch fixes these problems.

Also, as in GLibC, do not set orientation in ungetc, and only set, but
do not check orientation in ungetwc.

Fixes: 3d94e07c49 ("newlib: libc: Fix crash on fprintf to a wide-oriented stream.")
