bnxt_en: fix ternary sign extension bug in bnxt_show_temp()
The problem is that bnxt_show_temp() returns long but "rc" is an int
and "len" is a u32. With ternary operations the type promotion is quite
tricky. The negative "rc" is first promoted to u32 and then to long so
it ends up being a high positive value instead of a a negative as we
intended.
Fix this by removing the ternary.
