[PATCH v3 16/32] bootm: Move error printing out of boot_get_kernel()

[Simon Glass]

The same error message is printed in two places. Move it out to the
caller so we can avoid passing in the command name. Leave the bootstage
handling where it is.

Changes in v2:
- Use the command table to provide the command name, instead of "bootm"
