Convert properly UTF-8 to UTF-16

commit fd3ba42c76d3d4b776120c2b24c1791e7bb3deb1 upstream.

wchar_t is currently 16bit so converting a utf8 encoded characters not
in plane 0 (>= 0x10000) to wchar_t (that is calling char2uni) lead to a
-EINVAL return. This patch detect utf8 in cifs_strtoUTF16 and add special
code calling utf8s_to_utf16s.
