[U-Boot] [PATCH 1/3] BOOT: Fix unused variable issue when enabling bootz support

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

cmd_bootm.c: In function 'do_bootz':
cmd_bootm.c:1590:9: warning: variable 'iflag' set but not used [-Wunused-but-set-variable]

I think this is best taken through the Tegra tree, since it's needed to
avoid introducing warnings when enabling CONFIG_CMD_BOOTZ, which the next
patch enables, and we don't want MAKEALL -s tegra2 to suddenly start
giving warnings.
