xprtrdma: Remove Tavor MTU setting
Clean up. Remove HCA-specific clutter in xprtrdma, which is supposed to be device-independent. Hal Rosenstock <hal@dev.mellanox.co.il> observes: > Note that there is OpenSM option (enable_quirks) to return 1K MTU > in SA PathRecord responses for Tavor so that can be used for this. > The default setting for enable_quirks is FALSE so that would need > changing.
