[PATCH 11/23] lightnvm: remove unnecessary variables in rrpc

[Matias BjÃrling]

From: Javier GonzÃlez <jg@xxxxxxxxxxx>

Before vectored I/Os were supported on rrpc, the physical address was
stored as part of the nvm_rqd request. This variable become obsolete
when the ppa_list was introduced. Cleanup this variable.
