[v4,0/1] dax: enable dax fault handler to report VM_FAULT_HWPOISON

Message

Change from v3:
Prevent leaking EHWPOISON to user level block IO calls such as
zero_range_range, and truncate.  Suggested by Dan.

Change from v2:
Convert EHWPOISON to EIO to prevent EHWPOISON errno from leaking
out to block read(2). Suggested by Matthew.
