IB/core: Avoid unsigned int overflow in sg_alloc_table
commit 3c7ba5760ab8eedec01159b267bb9bfcffe522ac upstream.
sg_alloc_table gets unsigned int as parameter while the driver
returns it as size_t. Check npages isn't greater than maximum
unsigned int.
Fixes: eeb8461e36c9 ("IB: Refactor umem to use linear SG table")
