Avoid the inline ifdefs and use two sections for self-tests enabled and disabled. Though there could be no ifdef and unconditional test_bit of BTRFS_FS_STATE_DUMMY_FS_INFO, the static inline can help to optimize out any code that would depend on conditions using btrfs_is_testing. As this is only for the testing code, drop unlikely().
