Subject: [PATCH] ps3disk: Remove a superfluous cast

ps3disk: Remove a superfluous cast

As ps3disk is a ppc64-only driver, sector_t equals to unsigned long, and the
cast is not needed.

Reuse in another (possibly 32-bit) driver is protected by the safety net called
`compiler warning' (with the cast, it may silently truncate to 32-bit).
If sector_t ever changes, we will get a compiler warning as well (with the
cast, we won't).
