Alan Cox 20eec4bbdb Fix a deadlock between vm_fault() and vm_mmap(): The expected lock ordering ...

between vm_map and vnode locks is that vm_map locks are acquired first.  In
revision 1.150 mmap(2) was changed to pass a locked vnode into vm_mmap().
This creates a lock-order reversal when vm_mmap() calls one of the vm_map
routines that acquires a vm_map lock.  The solution implemented herein is
to release the vnode lock in mmap() before calling vm_mmap() and reacquire
this lock if necessary in vm_mmap().
