io_uring/rsrc: raise registered buffer 1GB limit

Browse source

There's no real reason to have a limit, as the memory is accounted by
the lockmem limits anyway, if any exist. io_pin_pages() will still
restrict the maximum allowed limit per buffer, which is INT_MAX
number of pages. Cap it a bit lower than that, at 1TB for a 64-bit
system. Surely that should be enough for everyone. For now.
