Subject: ixgbe: Fix an error handling path in ixgbe_read_iosf_sb_reg_x550()
Patch-mainline: v6.8-rc3
Git-commit: bbc404d20d1b46d89b461918bc44587620eda200
References: jsc#PED-4872
All error handling paths, except this one, go to 'out' where
release_swfw_sync() is called.
This call balances the acquire_swfw_sync() call done at the beginning of
the function.
Branch to the error handling path in order to correctly release some
resources in case of error.
Fixes: ae14a1d8e104 ("ixgbe: Fix IOSF SB access issues")
