[Qemu-devel] [PATCH v8 05/16] qapi: Drop useless gen_err_check()

[Eric Blake]

Ever since commit 12f254f removed the last parameterization
of gen_err_check(), it no longer makes sense to hide the three
lines of generated C code behind a macro call. Just inline it
into the remaining users.

No change to generated code.
