[SRU][noble:linux-azure][PATCH 1/2] RDMA/mana_ib: use the correct page table index based on hardware page size

[John Cabaj]

From: Long Li <longli at microsoft.com>

BugLink: https://bugs.launchpad.net/bugs/2084052

MANA hardware uses 4k page size. When calculating the page table index,
it should use the hardware page size, not the system page size.
