bnxt_en: Call bnxt_ethtool_free() in bnxt_init_one() error path

stable inclusion
from stable-5.10.46
commit c5d70dbc4d0b1dac909a7cb5a26b7c51fceacebe
bugzilla: 168323
CVE: NA

--------------------------------

[ Upstream commit 03400aaa ]

bnxt_ethtool_init() may have allocated some memory and we need to
call bnxt_ethtool_free() to properly unwind if bnxt_init_one()
fails.

Fixes: 7c380918 ("bnxt_en: Refactor bnxt_init_one() and turn on TPA support on 57500 chips.")
