staging: rdma: hfi1: file_ops: Replace ALIGN with PAGE_ALIGN

mm.h contains a helper function PAGE_ALIGN which aligns the pointer
to the page boundary instead of using ALIGN(expression, PAGE_SIZE)

This change was made with the help of the following Coccinelle
semantic patch:
//<smpl>
@@
expression e;
symbol PAGE_SIZE;
@@
(
- ALIGN(e, PAGE_SIZE)
+ PAGE_ALIGN(e)
|
- IS_ALIGNED(e, PAGE_SIZE)
+ PAGE_ALIGNED(e)
)
//</smpl>
