blockjob: introduce block_job _locked() APIs

Browse source 
Just as done with job.h, create _locked() functions in blockjob.h

These functions will be later useful when caller has already taken
the lock. All blockjob _locked functions call job _locked functions.

Note: at this stage, job_{lock/unlock} and job lock guard macros
are *nop*.
