Unlock request in PT using ocf_req_unlock()

Browse Source 
There are situations when we can end up in engine_pt with cache lines
locked for write. One example is engine_rd falling back to engine_pt after
failure during cache line preparation, where write lock has been already
taken. To handle this situation properly, unlock request using more general
unlock function.
