exec: Remove MemoryRegion::global_locking field

Browse source 
Last uses of memory_region_clear_global_locking() have been
removed in commit 7070e085d4 ("acpi: mark PMTIMER as unlocked")
and commit 08565552f7 ("cputlb: Move NOTDIRTY handling from I/O
path to TLB path").
Remove memory_region_clear_global_locking() and the now unused
'global_locking' field in MemoryRegion.
