xfs, proc: hide unused xfs procfs helpers
These two functions now trigger a warning when CONFIG_PROC_FS is disabled:
fs/xfs/xfs_stats.c:128:12: error: 'xqmstat_proc_show' defined but not used [-Werror=unused-function]
static int xqmstat_proc_show(struct seq_file *m, void *v)
^~~~~~~~~~~~~~~~~
fs/xfs/xfs_stats.c:118:12: error: 'xqm_proc_show' defined but not used [-Werror=unused-function]
static int xqm_proc_show(struct seq_file *m, void *v)
^~~~~~~~~~~~~
Previously, they were referenced from an unused 'static const' structure,
which is silently dropped by gcc.
We can address the warning by adding the same #ifdef around them that
hides the reference.
