nvmem: core: initialise nvmem->id early

nvmem: core: initialise nvmem->id early

commit 3bd747c7ea13cb145f0d84444e00df928b0842d9 upstream.

The error path for wp_gpio attempts to free the IDA nvmem->id, but
this has yet to be assigned, so will always be zero - leaking the
ID allocated by ida_alloc(). Fix this by moving the initialisation
of nvmem->id earlier.
