libata: Allow NCQ TRIM to be enabled or disabled with a module parameter
We have started seeing SSD firmware updates introduce support for queued TRIM. Sadly, in most cases this support is completely untested and can lead to either errors or data corruption. Add two libata force flags that can be used to either enable or disable queued TRIM support. Signed-off-by: Martin K.
