Log:
SVN rev 207700 on 2010-05-06 15:52:08Z by alc
Eliminate a small bit of unneeded code from kern_sendfile(): While
kern_sendfile() is running, the file's vm object can't be destroyed
because kern_sendfile() increments the vm object's reference count. (Once
kern_sendfile() decrements the reference count and returns, the vm object
can, however, be destroyed. So, sf_buf_mext() must handle the case where
the vm object is destroyed.)
