Looks good to me.

There is presently no limit for the max-recursion scan option.
Selecting a max-recursion limit that is too high will cause confusing
errors. E.g.:

/home/aragusa/install.alz/bin/clamscan -d clamav.hdb . --max-recursion=9999999999

LibClamAV Error: fmap_fd: Attempted to get fd for NULL fmap
/home/aragusa/issue/clamav.hdb: Can't allocate memory ERROR
LibClamAV Error: fmap_fd: Attempted to get fd for NULL fmap
/home/aragusa/issue/test.sh: Can't allocate memory ERROR

This commit prevents setting the max-recursion limit higher than 100.
