Merge: Revert "dma-mapping: reject __GFP_COMP in dma_alloc_attrs" and "cnic: don't pass bogus GFP_ flags to dma_alloc_coherent"

MR: https://gitlab.com/redhat/rhel/src/kernel/rhel-9/-/merge_requests/929

JIRA: https://issues.redhat.com/browse/RHEL-2542


Upstream Status: RHEL Only

This reverts commit a2cfbf05.
This reverts commit f7eaf7fc.

bnx2i/cnic currently fails to properly mmap its dma_alloc_coherent
buffers through a uio interface without being able to allocate compound
pages.  Revert this until we can get a better cnic fix.
