checkpatch: reduce is_maintained_obsolete lookup runtime
The is_maintained_obsolete function can be called twice using the same
filename. This function spawns a process using get_maintainer.pl.
Store the status of each filename when spawned and use the stored result
to eliminate the spawning of unnecessary duplicate child processes.
Example:
old:
$ time ./scripts/checkpatch.pl hp100-Move-to-staging.patch > /dev/null
real 0m1.767s
user 0m1.634s
sys 0m0.141s
new:
$ time ./scripts/checkpatch.pl hp100-Move-to-staging.patch > /dev/null
real 0m1.184s
user 0m1.085s
sys 0m0.103s
