Alexey Dobriyan 62ae1ea9da null_blk: fix spurious IO errors after failed past-wp access
[ Upstream commit ff77042296d0a54535ddf74412c5ae92cb4ec76a ]

Steps to reproduce:

	BLKRESETZONE zone 0

	// force EIO
	pwrite(fd, buf, 4096, 4096);

	[issue more IO including zone ioctls]

It will start failing randomly including IO to unrelated zones because of
->error "reuse". Trigger can be partition detection as well if test is not
run immediately which is even more entertaining.

The fix is of course to clear ->error where necessary.
