rocr: Remove extra check for page-aligned

ROCr initially had a bug where memory allocations that were not 4K
aligned were internally 4K aligned but ROCr would not keep track
of user-requested size. This would cause some pointer_info queries
to fail, but HIP was already aligning the buffer sizes for IPC
requests. For backward compatibility accross 2 minor versions,
we allowed IPC look-ups to be both aligned and un-aligned.
Removing this check as this 4 minor versions have been released
since then.
