replay: fix icount request when replaying clock access
Record/replay provides REPLAY_CLOCK_LOCKED macro to access the clock when vm_clock_seqlock is locked. This macro is needed because replay internals operate icount. In locked case replay use icount_get_raw_locked for icount request, which prevents excess locking which leads to deadlock. But previously only record code used *_locked function and replay did not. Therefore sometimes clock access lead to deadlocks. This patch fixes clock access for replay too and uses *_locked icount access function.
