Subject: net/mlx5e: Call mlx5e_page_release_dynamic directly where possible
Patch-mainline: v6.1-rc1
Git-commit: 96d37d861a09ba4b6ea08b87fa1c173c1af522b1
References: jsc#PED-1549

mlx5e_page_release calls the appropriate deallocator depending on
whether it's an XSK RQ or a regular one. Some flows that call this
function are not compatible with XSK, so they can call the non-XSK
deallocator directly to save a branch.
