    Bug 16168: Eliminate unneeded C4::Context->dbh calls in C4/Biblio.pm
    
    Right now, ->dbh calls are actually quite expensive (they involve
    DB connection health checks, each and every time). Some speed-sensitive
    subroutines inside C4/Biblio.pm (GetMarcStructure, GetAuthorisedValueDesc)
    have this statement
    
        my $dbh = C4::Context->dbh;
    
    on top of the code, but they don't always/don't usually need DB
    handle - not at that stage at least. This trivial patch eliminates
    unneeded ->dbh calls in those subroutines. With it, average
    GetMarcStructure() running time goes down from 14 miliseconds
    to 9 miliseconds (on top of Bug 16166), it also makes catalogue
    search profiling a bit easier.
    
    Test plan:
    
    1) apply patch
    2) ensure that catalogue searches are still working
    3) run t/*Biblio* tests
