Doing min_t(int, foo, INT_MAX) doesn't work correctly, because if foo
is bigger than INT_MAX, then when treated as a signed integer, it will
become negative and hence such an expression is just an elaborate NOP.
Fix such cases in ehca to do min_t(unsigned, foo, INT_MAX) instead.
This fixes negative reported values for max_cqe, max_pd and max_ah:
Before:
max_cqe: -64
max_pd: -1
max_ah: -1
After:
max_cqe: 2147483647
max_pd: 2147483647
max_ah: 2147483647
