CLEANUP: hlua: fix indent, remove extra return in hlua_core_get_var()

This is cleanup patch to address cosmetic issues introduced in f034139bc0
("MINOR: lua: Allow reading "proc." scoped vars from LUA core.")

Also taking this opportunity to prefix the function with __LJMP to
indicate that it may longjump.

No backport needed.
