Mike ChristieandMartin K. Petersen 255c4f4a6d block: Add error codes for common PR failures
If a PR operation fails we can return a device-specific error which is
impossible to handle in some cases because we could have a mix of devices
when DM is used, or future users like LIO only knows it's interacting with
a block device so it doesn't know the type.

This patch adds a new pr_status enum so drivers can convert errors to a
common type which can be handled by the caller.
