btrfs: tree-checker: fix bounds check in check_inode_extref()

Browse Source 
commit e92c2941204de7b62e9c2deecfeb9eaefe54a22a upstream.

The parentheses for the unlikely() annotation were put in the wrong
place so it means that the condition is basically never true and the
bounds checking is skipped.
