proc_init: Fix a few memory leaks of 'phdl'

Browse Source 
In the normal case and correct failure cases, the 'phdl' pointer is passed to
callers to use or clean up as needed.  However, some failure cases returned
early, failing to export the phdl pointer.

This was introduced in the restructuring of r303533.
