Jakub Kicinski 249801360d net: genl: fix error path memory leak in policy dumping 
If construction of the array of policies fails when recording
non-first policy we need to unwind.

netlink_policy_dump_add_policy() itself also needs fixing as
it currently gives up on error without recording the allocated
pointer in the pstate pointer.
