Fix error that caused seek format operations to set max file size to '1' or '0'

A very inappropriate placement of a ')' (introduced in r362151) caused the
maximum size of a file to be set as the result of a comparison operation, as
opposed to the result of the ftello operation.  This resulted in seeking being
restricted to the beginning of the file, or 1 byte into the file.  Thanks to
the Asterisk Test Suite for properly freaking out about this on at least one
test.
