net/mlx5: Clean up only new IRQ glue on request_irq() failure
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Clean up only new IRQ glue on request_irq() failure The mlx5_irq_alloc() function can inadvertently free the entire rmap and end up in a crash[1] when the other threads tries to access this, when request_irq() fails due to exhausted IRQ vectors. This commit modifies the cleanup to remove only the specific IRQ mapping that was just added. This prevents removal of other valid mappings and ensures precise cleanup of the failed IRQ allocation's associated glue object. Note: This error is observed when both fwctl and rds configs are enabled.
