[PATCH 2/3] ipr: dlpar failed when adding an adapter back

[wenxiong@linux.vnet.ibm.com]

[-- Attachment #1: reinit_used_res_q --]
[-- Type: text/plain, Size: 883 bytes --]

Reinitialize resource queue prior to freeing resource entries to ensure they
are not referenced. This fixes an issue with target_destoy accessing memory
after it was freed.
