Subject: net/mlx5: Fix arm SRQ command for ISSI version 0

From: Noa Osherovich <[email protected]>

[ Upstream commit 672d0880b7798a917bcc622308f25a0fbb991dab ]

Support for ISSI version 0 was recently broken as the arm_srq_cmd command, which is used only for ISSI version 0, was given the opcode for ISSI version 1 instead of ISSI version 0.

Change arm_srq_cmd to use the correct command opcode for ISSI version 0.
