kernel: dma: fix call order in dmam_free_coherent

A vulnerability was found in the Linux kernel's dma subsystem in the dmamfreecoherent function where a race condition is possible between the calls to dmamfreecoherent and devresdestroy leading to a double entry in the devres list. This flaw could potentially lead to memory corruption or unexpect...
