ANDROID: GKI: Update .stg file based on io_ring_ctx internal change

In commit 9aeb6833 ("io_uring: get rid of remap_pfn_range() for
mapping rings/sqes") struct io_ring_ctx had some new fields added to fix
some security issues.  This is an internal-to-the-io_uring-core
structure, but happens to have a pointer to this structure in other
structures that we track for ABI compliance.  Because this is not an
"anonymous" pointer, it breaks the ABI checking.  But as this is an
internal structure it is safe to change as no external module ever
accesses this structure at all.

The .stg update is:

type 'struct io_ring_ctx' changed
  byte size changed from 1344 to 1408
  member 'unsigned short n_ring_pages' was added
  member 'unsigned short n_sqe_pages' was added
  member 'struct page** ring_pages' was added
  member 'struct page** sqe_pages' was added
