submodule--helper: fix a memory leak in print_status()
Fix a leak in print_status(), the compute_rev_name() function
implemented in this file will return a strbuf_detach()'d value, or
NULL.
This leak has existed since this code was added in
a9f8a37584a (submodule: port submodule subcommand 'status' from shell
to C, 2017-10-06), but in 0b5e2ea7cf3 (submodule--helper: don't print
null in 'submodule status', 2018-04-18) we added a "const"
intermediate variable for the return value, that "const" should be
removed.
