net/mlx5e: Fix NULL pointer dereference in ioctl module EEPROM query
The mlx5_query_mcia() function unconditionally dereferences the status
pointer to store the MCIA register status value.
However, mlx5e_get_module_id() passes NULL since it doesn't need the
status value.
Add a NULL check before dereferencing the status pointer to prevent a
NULL pointer dereference.
Fixes: 2e4c44b12f4d ("net/mlx5: Refactor EEPROM query error handling to return status separately")
