linuxkpi: Add mmap_lock.h This contain mmap_read_lock, mmap_read_unlock and mmap_write_lock_killable which are abstraction around down_read, up_read and down_write_killable. Note that in Linux 5.8 mmap_sem was renamed to mmap_lock. We might want to do the same at some point but some drivers still uses the old mmap locking API.
