[Patch][gdb] Initialise quiet flag for "info functions"

[Matthew Malcomson]

With this flag unset, using 'info functions' without a set quiet flag
was not deterministic and was causing some flaky test failures.

Failures seen in (at least).
gdb.base/info_qt.exp
gdb.dwarf2/dw2-case-insensitive.exp
gdb.base/info-fun.exp

Ok for trunk?
I don't have commit rights.
