Allow to control failfast
Linux defaults to setting "failfast" on BIOs, so that the OS will not
retry IOs that fail, and instead report the error to ZFS.

In some cases, such as errors reported by the HBA driver, not
the device itself, we would wish to retry rather than generating
vdev errors in ZFS. This new property allows that.

This introduces a per vdev option to disable the failfast option.
This also introduces a global module parameter to define the failfast
mask value.
