sdong 7f08a8503f Remove IOSTATS_ADD_IF_POSITIVE() (#8984)
Summary:
IOSTATS_ADD_IF_POSITIVE() doesn't seem to a macro that aims to improve performance but does the opposite. The counter to add is almost always positive so the if is just a waste. Furthermore, adding to a thread local variable seemse to be much cheaper than an if condition if branch prediction has a possibility to be wrong. Remove the macro.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/8984

Test Plan: See CI completes.
