Save code size by calling get_type only once

Browse Source 
This is an external function, so in the absence of link-time
optimisation (LTO) the compiler can't know anything about it and has to
call it the number of times it's called in the source code.

This only matters for pk_ec, but change pk_rsa as well for the sake of
uniformity.
