Ethtool core stores indirection table with u32 entries, "just to be safe".
Switch the type in the driver, so that it's easier to swap local tables
for the core ones. Memory allocations already use sizeof(*entry), switch
the memset()s as well.

Signed-off-by: Jakub Kicinski <kuba@kernel.org>

v2:
 - switch from sizeof(u32) to sizeof(*indir_tbl)
 - add a sentence to the commit msg
