VOP_GETATTR() wants the vnode passed to it to be locked. Instead

Browse source 
of adding the code to lock and unlock the vnodes and taking care
to avoid deadlock, simplify linux_emul_convpath() by comparing the
vnode pointers directly instead of comparing their va_fsid and
va_fileid attributes.  This allows the removal of the calls to
VOP_GETATTR().
