RDMA/odp: Add missing cast for 32 bit
length is a size_t which is unsigned int on 32 bit:
../drivers/infiniband/core/umem_odp.c: In function 'ib_init_umem_odp':
../include/linux/overflow.h:59:15: warning: comparison of distinct pointer types lacks a cast
59 | (void) (&__a == &__b); \
| ^~
../drivers/infiniband/core/umem_odp.c:220:7: note: in expansion of macro 'check_add_overflow'
Fixes: 204e3e5630c5 ("RDMA/odp: Check for overflow when computing the umem_odp end")
