LU-4277 lod: handle os_state as a flag, check READONLY
Handle the osfs->os_state values as flags instead of as values.
Otherwise, if an OSD has OS_STATE_DEGRADED and another flag set
it will not match to skip the OST during object allocation.
Similarly, there was no check for the OS_STATE_READONLY flag in
the create path, which should be used to always skip an OST for
object creation until it is cleared.
These flags are not yet set by osd-zfs, only by osd-ldiskfs so far.
