net/mlx5: Fix error print in case of IRQ request failed
[ Upstream commit aa968f922039706f6d13e8870b49e424d0a8d9ad ]
In case IRQ layer failed to find or to request irq, the driver is
printing the first cpu of the provided affinity as part of the error
print. Empty affinity is a valid input for the IRQ layer, and it is
an error to call cpumask_first() on empty affinity.
Remove the first cpu print from the error message.
Fixes: c36326d38d93 ("net/mlx5: Round-Robin EQs over IRQs")
