An incorrect sizeof is being used, u64 * is not correct, it should be
just u64 for a table of umem_pgs number of u64 items in the pbl_tbl.
Use the idiom sizeof(*pbl_tbl) to get the object type without the need
to explicitly use u64.

Addresses-Coverity: ("Sizeof not portable (SIZEOF_MISMATCH)")
Fixes: 1ac5a4047975 ("RDMA/bnxt_re: Add bnxt_re RoCE driver")
