Mark Johnston 300cfb96fc file: Make fget*() and getvnode*() consistent about initializing *fpp 
Most fget*() functions initialize the output parameter to NULL.  Make
the externally visible interface behave consistently, and make
fget_unlocked_seq() private to kern_descrip.c.

This fixes at least one bug in a consumer, _filemon_wrapper_openat(),
which assumes that getvnode() sets the output file pointer to NULL upon
an error.
