artik530: configs: clear local variable after load_fdt

This patch clears local variables such as success, number and loop of
load_fdt command to avoid invalid environment corruption. After
execution "run load_fdt" command on the u-boot shell, it will keep the
local variables. When a user run "saveenv" command in the situation,
it will cause invalid fdt load due to dirty local variables.
