bnxt_en: Fix IRQ coalescing regression.
Recent IRQ coalescing clean up has removed a guard-rail for the max DMA
buffer coalescing value. This is a 6-bit value and must not be 0. We
already have a check for 0 but 64 is equivalent to 0 and will cause
non-stop interrupts. Fix it by adding the proper check.
Fixes: f8503969d27b ("bnxt_en: Refactor and simplify coalescing code.")
