Reduce unnecessary get_name() function calls

alpm_pkg_get_name() gives us little benefit in backend code besides a NULL
check on the package passed in; we could do that ourself if necessary. By
changing to direct references in the cases where we are sure we have a valid
package, we save a function call each time we need a package name. This
function can't be inlined because it is externally accessible.

This cuts the calls to get_name() from 1.3 million times in a
pacman -Qu operation to around 2400.
