swtpm_setup: Initialize pubek_len (Coverity)

Initialize pubek_len even though it isn't necessary to do so since
it will be initialized in the first function to which it is passed.
However, Coverity complains about pubek_len passed to print_as_hex()
not being initialized, even though this is not possible.
