ALSA: control: remove compilation warning on 32-bit
This was introduced by 'ALSA: control: add support for ENUMERATED user
space controls' which adds a u64 variable that gets cast to a pointer:
sound/core/control.c: In function 'snd_ctl_elem_init_enum_names':
sound/core/control.c:1089: warning: cast to pointer from integer of different size
Cast to uintptr_t before casting to pointer to avoid the warning.

[cl: replace long with uintptr_t]
