[PATCH] common/cnxk: fix uninitialized pointers in NPA context dump

[Nawal Kishor]

In roc_npa_ctx_dump(), rsp and rsp_cn20k are only set through
mbox_process_msg() in separate branches, while the dump code that reads
them selects the pointer in a different branch. The compiler cannot
prove that the pointer being read was set, and warns about a possibly
uninitialized variable.

Initialize both pointers to NULL.

Fixes: a7cc84c6e9e5 ("common/cnxk: support HALO in NPA")
