Subject: [PATCH] nvme-pci: remove two deallocate zeroes quirks
The quirk was initially used as a signal to set the discard_zeroes_data
queue limit because there were some use cases that relied on that
behavior. The queue limit no longer exists as every user of it has been
converted to use the write zeroes operation instead.
The quirk now means to use a discard command as an alias to a write
zeroes request. Two of the devices previously using the quirk support
the write zeroes command directly, so these don't need or want to use
discard when the desired operation is to write zeroes.
