mtd: rawnand: atmel: Fix possible memory leak
The pmecc "user" structure is allocated in atmel_pmecc_create_user() and
was supposed to be freed with atmel_pmecc_destroy_user(), but this other
helper is never called. One solution would be to find the proper
location to call the destructor, but the trend today is to switch to
device managed allocations, which in this case fits pretty well.
Replace kzalloc() by devm_kzalloc() and drop the destructor entirely.
