Suppress maybe-uninitialized warning.

Browse Source 
Following commit e035863c9a0, building with -O0 began triggering
warnings about potentially uninitialized 'workbuf' usage. While
theoretically the initialization isn't necessary since VARDATA()
doesn't access the contents of the pointed-to object, this commit
explicitly initializes the workbuf variable to suppress the warning.

Buildfarm members adder and flaviventris have shown the warning.
