BUG/MINOR: worker: Missing calloc return value check in mworker_env_to_proc_list

A memory allocation failure happening in mworker_env_to_proc_list when
trying to allocate a mworker_proc would have resulted in a crash. This
function is only called during init.

It was raised in GitHub issue #1233.
It could be backported to all stable branches.
