mtd: sm_ftl: Staticize local symbols 



These local symbols are used only in this file.
Fix the following sparse warnings:

drivers/mtd/sm_ftl.c:25:25: warning: symbol 'cache_flush_workqueue' was not declared. Should it be static?
drivers/mtd/sm_ftl.c:44:9: warning: symbol 'sm_attr_show' was not declared. Should it be static?
drivers/mtd/sm_ftl.c:57:24: warning: symbol 'sm_create_sysfs_attributes' was not declared. Should it be static?
drivers/mtd/sm_ftl.c:110:6: warning: symbol 'sm_delete_sysfs_attributes' was not declared. Should it be static?
drivers/mtd/sm_ftl.c:574:5: warning: symbol 'sm_get_media_info' was not declared. Should it be static?
drivers/mtd/sm_ftl.c:881:17: warning: symbol 'sm_get_zone' was not declared. Should it be static?
