[U-Boot] [PATCH] common/cmd_load.c - More code cleanup

[Gururaja Hebbar K R]

- Remove unused global variable os_data_count.
   This was long back deprecated but still in use.
   The only reference for this in google is 
   http://cvs.tuxbox.org/cgi-bin/viewcvs.cgi/*checkout*/tuxbox/boot/ppcboot/common/Attic/cmd_boot.c?content-type=text%2Fplain
 - Remove unused variable z. its just incremented.
