media: chips-media: wave5: Release m2m_ctx after Instance Removed from List
Possible use after free if IRQ thread manages to obtain spinlock between
m2m_ctx release and wave5_release function removing stream instance from
list of active instances. The IRQ thread looks for the m2m_ctx which is
freed so null pointer dereference occurs.
