[U-Boot] [PATCH v2 01/18] main: Use conditional run_preboot_environment_command()

[Simon Glass]

The function name indicates that it does something, but its entire
operation is actually condition on a CONFIG. Move the condition outside
the function so this is clearer, and use if() instead of #ifdef, like the
reset of the file.
