Jie Deng dba49b38df hv: add bitmap_clear_lock of split-lock after completing emulation ...

Suppose the current vcpu is 0, the other vcpus (1, 2, 3) may wait on the
"get_split_lock", the current vcpu need clear the ACRN_REQUEST_SPLIT_LOCK
explicitly here after finishing the emulation. Otherwise, it make cause
dead lock. for example:
	1. Once vcpu 0 "put_split_lock", let's say vcpu 1 will "get_split_lock".
	2. vcpu 1 call "vcpu_make_request" to pause vcpu 0, 2, 3.
	3. vcpu 1's VCPU_EVENT_SPLIT_LOCK is still not cleared because
	   the vcpu 0 called "vcpu_make_request" ever.
	4. All vcpus will wait for VCPU_EVENT_SPLIT_LOCK in acrn_handle_pending_request.
We should avoid this dead lock case.

Please note: this patch is only for release 2.5 test.
