ubik: do not reuse the offset variable for the sync site address
The ubik SendFile function performs a sanity check of the host address
before proceeding with the file transfer. Currently this check reuses
the file offset local variable to hold the value of the sync site
address, a 32-bit IPv4 address. Not only is this confusing, but also
causes a signed/unsigned type mismatch when comparing host addresses.
Instead of being so stingy with local variables, declare a new local
variable of the correct type to hold the value of the sync site address.
This separation is also a prerequisite for supporting larger address
types in the future.
