[PATCH] staging/rtl8192u: hide unused procfs helpers

[YueHaibing]

When CONFIG_PROC_FS isn't set, gcc warning this:

drivers/staging/rtl8192u/r8192U_core.c:508:12: warning: âproc_get_stats_apâ defined but not used [-Wunused-function]
 static int proc_get_stats_ap(struct seq_file *m, void *v)
            ^
drivers/staging/rtl8192u/r8192U_core.c:527:12: warning: âproc_get_registersâ defined but not used [-Wunused-function]
 static int proc_get_registers(struct seq_file *m, void *v)
            ^

 static int proc_get_stats_tx(struct seq_file *m, void *v)
            ^
drivers/staging/rtl8192u/r8192U_core.c:627:12: warning: âproc_get_stats_rxâ defined but not used [-Wunused-function]
 static int proc_get_stats_rx(struct seq_file *m, void *v)
            ^
fix this by adding #ifdef around them.
