Matan Azrad 8dc775d8b1 net/mlx5: fix event queue number query
When a Rx\Tx queue is created by DevX, its CQ configuration should
include the EQ number of the interrupts.
The EQ is managed by the kernel and there is a glue API in order to
query the EQ number from the kernel.
The EQ query API gets a vector number specifies the kernel vector of
the interrupt handling.

The vector number was wrongly detected according to the configuration
CPU instead of using the device attributes of the supported vectors.
The CPU was wrongly detected by the rte_lcore_to_cpu_id API without any
check, and in case of non-EAL thread context the value was 0xFFFFFFFF
which caused a failure in the EQ number query API.

Use vector 0 for each EQ number query which must be supported by the
kernel.
