mlx4_core: Fix integer overflows so 8TBs of memory registration works
This patch adds on the fixes done in commits 89dd86db78e0 ("mlx4_core:
Allow large mlx4_buddy bitmaps") and 3de819e6b642 ("mlx4_core: Fix
integer overflow issues around MTT table") so that memory registration
of up to 8TB (log_num_mtt=31) finally works.
It fixes integer overflows in a few mlx4_table_yyy routines in icm.c
by using a u64 intermediate variable, and int/uint issues that caused
table indexes to become nagive by setting some variables to be u32
instead of int. These problems cause crashes when a user attempted to
register > 512GB of RAM.
