bnxt: disable napi before canceling DIM

Browse Source 
[ Upstream commit 01cca6b9330ac7460de44eeeb3a0607f8aae69ff ]

napi schedules DIM, napi has to be disabled first,
then DIM canceled.

Noticed while reading the code.

Fixes: 0bc0b97fca ("bnxt_en: cleanup DIM work on device shutdown")
Fixes: 6a8788f256 ("bnxt_en: add support for software dynamic interrupt moderation")
