btrfs: make sure report_eb_range() is not inlined

If report_rb_range() is inlined into its single caller (check_eb_range()),
we end up with a larger module size, which is undesirable and does not
provide any advantage since this code is for a cold path which we don't
expect to ever hit.

Add the noinline attribute to report_rb_range() and while at it also make
it return void as it always returns true.

Before this change (with gcc 14.2.0-19 from Debian):

  $ size fs/btrfs/btrfs.ko
     text	   data	    bss	    dec	    hex	filename
  2018267	 176232	  15592	2210091	 21b92b	fs/btrfs/btrfs.ko

After this change:

  $ size fs/btrfs/btrfs.ko
     text	   data	    bss	    dec	    hex	filename
  2017835	 176048	  15592	2209475	 21b6c3	fs/btrfs/btrfs.ko

Also, replacing the noinline with __cold, yields slighty worse results:

  $ size fs/btrfs/btrfs.ko
     text	   data	    bss	    dec	    hex	filename
  2017889	 176048	  15592	2209529	 21b6f9	fs/btrfs/btrfs.ko
