Convert error getting device IDs in ocl code to info log level only since multiple platforms may be installed and the error is harmless there.

Remove the rounding-up of the scrypt padbuffer which was not effectual and counter-productive on devices with lots of ram, limiting thread concurrencies and intensities.

Revert "Pick worksize 256 with Cypress if none is specified."
...
This reverts commit 482322a4b7add8458bee946ffb247a9a587fc25f.
Worksize 256 was only helpful on cypress with ultra-low memory speeds with old SDKs and the new kernels require higher memory clocks, having the opposite net effect.
