[SRU][N:linux-bluefield][PATCH v1 0/1] RDMA/mlx5: Fix mlx5_poll_one() cur_qp update flow

[Stav Aviram]

BugLink: https://bugs.launchpad.net/bugs/2126876

SRU Justification:

[IMPACT]
Introduce an upstream patch series that was previously integrated into linux-bluefield-5.15 (Ubuntu 22.04 Jammy) into linux-bluefield-6.8 (Ubuntu 24.04 Noble), in order to minimize the divergence between the two kernel versions.
This patch fixes the cur_qp update flow in mlx5_poll_one() to prevent race conditions and incorrect queue pair state transitions.

[FIX]
Cherry-pick the following patches:

[TEST CASE]
Successfully compiled on linux-bluefield-6.8, master-next branch.

[Regression Potential]
Very low, as the series originates from upstream and has already been integrated into Jammy without reported issues.
