interconnect: Fix undersized devress_alloc allocation

commit 85b1ebf upstream.

The expression sizeof(**ptr) for the void **ptr is just 1 rather than
the size of a pointer. Fix this by using sizeof(*ptr).

Addresses-Coverity: ("Wrong sizeof argument")
Fixes: e145d9a ("interconnect: Add devm_of_icc_get() as exported API for users")
