hw/block/nvme: Separate read and write handlers
The majority of code in nvme_rw() is becoming read- or write-specific. Move these parts to two separate handlers, nvme_read() and nvme_write() to make the code more readable and to remove multiple is_write checks that has been present in the i/o path. This is a refactoring patch, no change in functionality.
