Subject: net/mlx4_core: Fix wrong calculation of free counters
Patch-mainline: v4.15-rc4
Git-commit: 0bb9fc4f5429ac970181c073aa32e521e20f7b73
References: bsc#1046300 FATE#322946
The field res_free indicates the total number of counters which are
available for allocation (reserved and unreserved). Fixed a bug where
the reserved counters were subtracted from res_free before any
allocation was performed.
Before this fix, free counters which were not reserved could not be
allocated.
