net/mlx5: Refactor completion IRQ request/release API
Introduce a per-vector completion IRQ request API that requests a
single IRQ for a given vector index instead of multiple IRQs request API.
On driver load, loop over all completion vectors and request an IRQ for
each one via the newly introduced API.
Symmetrically, introduce an IRQ release API per vector. On driver
unload, loop over all vectors and release each completion IRQ via
the new per-vector API.
As IRQ vectors will be requested dynamically later in the patchset,
add a cpumask of the bounded CPUs to avoid the possible mapping of
two IRQs of the same device to the same cpu.
