IB/hfi1: use size_t for passing array length
gcc-7 produces a mysterious warning about the size argument being potentially out
of range:
drivers/infiniband/hw/hfi1/verbs.c: In function 'init_cntr_names':
drivers/infiniband/hw/hfi1/verbs.c:1644:2: error: 'memcpy': specified size between 18446744071562067968 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Werror=stringop-overflow=]
This seems to refer to a the case where an 64-bit size_t gets truncated
into a negative 'int' and subsequently turned into a high 64-bit number
again.
The fix is clearly to use size_t here, which matches the type that gets
used for this value elsewhere.
