The "msh" pointer is device managed, meaning that memstick_alloc_host()
calls device_initialize() on it. That means that it can't be free
using kfree() but must instead be freed with memstick_free_host().
Otherwise it leads to a tiny memory leak of device resources.
Fixes: 60fdd931d577 ("memstick: add support for JMicron jmb38x MemoryStick host controller")
