core: syscall_storage_next_enum() use live pobj
Instead of using a fake pobj in syscall_storage_next_enum() retrieve the
shared pobj instead in order to get the flags of an already opened
object.
TEE_POBJ_USAGE_ENUM is supplied to tee_pobj_get() to avoid checking for
conflicts with how the pobj is already used.
