    fs/fs: Fix registration of mcumgr fs_mgmt group
    
    Since file system entity rework (commit a2dbdfdba "fs: Introduce file
    system entity") fs_mgmt_register_group() is never called and FS_MGMT
    group was not available over SMP. Also build with FS_MGMT enabled was
    failing due to unused g_mgmt_initialized variable.
    
    This restores previous behavior and registers fs_mgmt group when first
    file system is successfully mounted.
