Silence a spurious compiler warning
In some configurations, when using gcc 13.2.0, the compiler can
warn that the variable `error` in sync_fpmt_workers may be used
without being initialized.
This is a spurious warning - in fact, the compiler seems to be
able to tell that this code is fine in normal builds, and only
produces a warning when building with optimizations and assertions
both enabled, e.g.:
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DAOM_EXTRA_C_FLAGS="-UNDEBUG"
Prevent this warning by adding an explicit initializer.
