Mateusz Guzik 91e27ed8a3 lockref: tidy up dead count handling 
1. put the dead val into a macro so that it can be used in other places
2. __lockref_is_dead():
- drop the __ suffix, this is not an internal routine
- drop the spurious cast, the value is already a signed int
- use READ_ONCE to prevent any compile shenanigans
3. provide lockref_is_dead_or_zero()
