Renaming hash bucket locking functions

Browse Source 
1. new abbreviated previx: ocf_hb (HB stands for hash bucket)
2. clear distinction between functions requiring caller to
   hold metadata shared global lock ("naked") vs the ones
   which acquire global lock on its own ("prot" for protected)
3. clear distinction between hash bucket locking functions
   accepting hash bucket id ("id"), core line and lba ("cline")
   and entire request ("req").

Resulting naming scheme:
ocf_hb_(id/cline/req)_(prot/naked)_(lock/unlock/trylock)_(rd/wr)
