Revert "sys/linux: add description for fsinfo"

The fsinfo() system call is under heavy discussion upstream, and it
might be totally changed. As a result it was dropped from linux-next
starting in next-20200819, and the pull request for 5.9
(https://lkml.kernel.org/r/1845353.1596469795@warthog.procyon.org.uk/)
wasn't accepted. Therefore revert the syscall description (commit
4b0871d) for now.
