staging: vchiq_arm: Use devm_kzalloc() for drv_mgmt allocation
The struct drv_mgmt 'mgmt' is currently allocated dynamically using
kzalloc(). Unfortunately, it is subjected to memory leaks in the error
handling paths of the probe() function.
To address this issue, use device resource management
helper devm_kzalloc(), to ensure cleanup after the allocation.
