Linux 5.15 compat: block device readahead 
The 5.15 kernel moved the backing_dev_info structure out of
the request queue structure which causes a build failure.

Rather than look in the new location for the BDI we instead
detect this upstream refactoring by the existance of either
the blk_queue_update_readahead() or disk_update_readahead()
functions.  In either case, there's no longer any reason to
manually set the ra_pages value since it will be overridden
with a reasonable default (2x the block size) when
blk_queue_io_opt() is called.

Therefore, we update the compatibility wrapper to do nothing
for 5.9 and newer kernels.  While it's tempting to do the
same for older kernels we want to keep the compatibility
code to preserve the existing behavior.  Removing it would
effectively increase the default readahead to 128k.
