Armin Wolf 680f728901 fs/nls: Fix inconsistency between utf8_to_utf32() and utf32_to_utf8() 
[ Upstream commit c36f9d7b28 ]

After commit 25524b6190 ("fs/nls: Fix utf16 to utf8 conversion"),
the return values of utf8_to_utf32() and utf32_to_utf8() are
inconsistent when encountering an error: utf8_to_utf32() returns -1,
while utf32_to_utf8() returns errno codes. Fix this inconsistency
by modifying utf8_to_utf32() to return errno codes as well.

Fixes: 25524b6190 ("fs/nls: Fix utf16 to utf8 conversion")
