[Tarantool-patches] [PATCH luajit 1/3] misc: fix build with disabled memory profiler

[Sergey Kaplun]

This patch fixes the regression introduced in scope of
b4e6bf0d82100049d29af1aa3196e781270f39d1 ('misc: add Lua API for memory
profiler'). Build is failed with disabled memory profiler because
related error messages are not defined.

This patch fixes build by making LJ_ERR_PROF_MISUSE visible and avoiding
usage of other profiler-related errors when the profiler is disabled.
