fs: fix config name for smartfs exclusion from procfs
Smartfs info can be excluded from procfs by enabling
FS_PROCFS_EXCLUDE_SMARTFS config, but in smartfs_procfs
there was syntax error with wrong config name.
#include <arch/irq.h>
#include "smartfs.h"
-#if defined(CONFIG_FS_PROCFS) && !defined(CONFIG_FS_EXCLUDE_SMARTFS)
+#if defined(CONFIG_FS_PROCFS) && !defined(CONFIG_FS_PROCFS_EXCLUDE_SMARTFS)
