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


[ Upstream commit 672d0880 ]

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.

Fixes: af1ba291 ('{net, IB}/mlx5: Refactor internal SRQ API')
