iwlwifi: pcie: Configure shared interrupt vector in MSIX mode
In case the OS provides fewer interrupts than requested, different
causes will share the same interrupt vector as follow:
1.One interrupt less: non rx causes shared with FBQ.
2.Two interrupts less: non rx causes shared with FBQ and RSS.
3.More than two interrupts: we will use fewer RSS queues.
Also make the request depend on the number of online CPUs
instead of possible CPUs.
