John Baldwin e4ca250d4b - Obtain Giant in mmap() syscall while messing with file descriptors and ...

vnodes.
- Fix an old bug that would leak a reference to a fd if the vnode being
  mmap'd wasn't of type VREG or VCHR.
- Lock Giant in vm_mmap() around calls into the VM that can call into
  pager routines that need Giant or into other VM routines that need
  Giant.
- Replace code that used a goto to jump around the else branch of a test
  to use an else branch instead.
