Christophe Lombard 4fc0870d7e cxl: Fix memory page not handled 
The in-kernel 'library' API can be called by drivers to help
interaction with an IBM XSL on a POWER9 system.

The cxllib_handle_fault() API is used to handle memory fault. All memory
pages of the specified buffer have to be handled but under certain
conditions,the last page may not be touched, and the address the
adapter is trying to access is never sent to the kernel for resolution.

This patch reworks start address of the loop with an address aligned on
the page size. In this context, the last page is not missed.
