The two new variables are only used in an #ifdef, so they cause a
warning without CONFIG_QUOTA:
fs/ext4/super.c: In function 'parse_options':
fs/ext4/super.c:1977:26: error: unused variable 'grp_qf_name'
[-Werror=unused-variable]
char *p, *usr_qf_name, *grp_qf_name;
^~~~~~~~~~~
fs/ext4/super.c:1977:12: error: unused variable 'usr_qf_name'
[-Werror=unused-variable]
char *p, *usr_qf_name, *grp_qf_name;
Fixes: 20cefcdc2040 ("ext4: fix use-after-free race in ext4_remount()'s error
path")
