cxl/hdm: Fix skip allocations vs multiple pmem allocations

Vishal notes that when attempting to define a second pmem region on a
device the DPA allocation fails with a message of the form:

    decoder11.1: failed to reserve skipped space

Recall that the skip setting is used when there is a pmem allocation in
the presence of free ram DPA space. The first pmem allocation skips over
the free ram and subsequent pmem allocations do not require a skip. The
bug is that a skip is still attempted and the DPA reservation code
flags the double skip allocation conflict.
