mtd: Fix get_mtdparts()

When ENV_IS_IN_UBI is enable, get_mtdparts is called before relocation.

During first get_mtdparts() call, mtdparts is not available in environment,
it can be retrieved by calling board_mtdparts_default(), but following
env_set() do nothing as we are before relocation. Finally mtdparts is
still not available in environment.

At second get_mtdparts() call, use_defaults is false, but mtdparts is still
not in environment and is NULL.

Remove use_defaults bool, only mtdparts criteria is useful.

Fixes: commit 5ffcd50612f6 ("mtd: Use default mtdparts/mtids when not defined
in the environment")
