Only print the errno string in case sysctl(3) does not file with ENOENT
This reduces the noise in error reporing from sysctl(8):

Before:
$ sysctl bla=something
sysctl: unknown oid 'bla': No such file or directory

After:
$ sysctl bla=something
sysctl: unknown oid 'bla'

Make Tflag and Wflag filters work for more sysctl options.

2012-12-12T02:55:40+00:00

To do this move the Tflag and Wflag checks earlier in show_var() so
we bail earlier for variables not matching our query.
