    vfs: remove dead fifoop VOP_KQFILTER implementations
    
    These began to become obsolete in d6d64f0f2c26 (r137739) and the deal
    was later sealed in 003e18aef4c4 (r137801) when vfs.fifofs.fops was
    dropped and vop-bypass for pipes became mandatory.
    
    PR:             225934
    
    (cherry picked from commit 6b88668f0bfcca09035549e25d0f3c181cd537c8)
