[PATCH] btrfs: extent_buffer_uptodate() make it static and inline

[Anand Jain <anand.jain@oracle.com>]

extent_buffer_uptodate() is a trivial wrapper around test_bit()
and nothing else. So make it static and inline, save on code
space and call indirection.

Before:
   text	   data	    bss	    dec	    hex	filename
1131257	  82898	  18992	1233147	 12d0fb	fs/btrfs/btrfs.ko

After:
   text	   data	    bss	    dec	    hex	filename
1131090	  82898	  18992	1232980	 12d054	fs/btrfs/btrfs.ko
