6.1-stable review patch. If anyone has any objections, please let me know.

From: Ming Lei ming.lei@redhat.com
[ Upstream commit cdf07f0ea48a3b52f924714d477366ac510ee870 ]
The 'firstvec' parameter is always same with the parameter of 'startvec', so use 'startvec' directly inside irq_build_affinity_masks().
