[U-Boot] [PATCH v8 2/4] cmd: ubifs: Move ubifs_initialized checking into cmd_ubifs_umount()

[tien . fong . chee]

From: Tien Fong Chee 

cmd_ubifs_umount() function would be called directly instead of involving
whole command machinery in generic firmware loader, so checking on
ubifs_initialized status need to be done in cmd_ubifs_umount() without
breaking original functionality design.
