[PATCH 2/2] submodule::module_clone(): silence die() message from module_name()

[Tay Ray Chuan <rctay89@gmail.com>]

The die() message that may occur in module_name() is not really relevant
to the user when called from module_clone(); the latter handles the
"failure" (no submodule mapping) anyway.

Leave other callers of module_name() unchanged, as the die() message
shown is either relevant for user consumption (such as those that exit()
when the call fails), or will not occur at all (when called with paths
returned by module_list()).
