[OpenAFS] backup command crashes on amd64_linux26, passing integer 0 instead of NULL pointer

[Rainer Toebbicke]

The backup command crashes on amd64_linux26 when starting a dump.
Reason: an integer '0' passed instead of NULL for the 'newExt' 
parameter on bc_StartDmpRst().

See attached patch.

Bcc'ed to openafs-bugs.
