Fix build warnings in locale/programs/ld-ctype.c
This patch fixes the gcc warnings seen with gcc 9 -march>=z13 on s390x:
programs/ld-ctype.c: In function ‘ctype_read’:
programs/ld-ctype.c:1392:13: error: ‘wch’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
1392 | uint32_t wch;
| ^~~
programs/ld-ctype.c:1401:7: error: ‘seq’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
1401 | if (seq != NULL && seq->nbytes == 1)
| ^
programs/ld-ctype.c:1391:20: note: ‘seq’ was declared here
1391 | struct charseq *seq;
| ^~~
Both seq and wch are uninitialized if get_character fails.
Thus we are now returning with an error.
ChangeLog:
* locale/programs/ld-ctype.c (charclass_symbolic_ellipsis):
Return error if get_character fails.
