Liu Bo cb0acb3701 badblocks: fix wrong return value in badblocks_set if badblocks are disabled 
[ Upstream commit 39b4954c0a ]

MD's rdev_set_badblocks() expects that badblocks_set() returns 1 if
badblocks are disabled, otherwise, rdev_set_badblocks() will record
superblock changes and return success in that case and md will fail to
report an IO error which it should.

This bug has existed since badblocks were introduced in commit
9e0e252a04 ("badblocks: Add core badblock management code").
