[PATCH net 4/9] net/mlx5: HWS, Init mutex on the correct path

[Mark Bloch]

From: Vlad Dogaru <vdogaru@xxxxxxxxxx>

The newly introduced mutex is only used for reformat actions, but it was
initialized for modify header instead.

The struct that contains the mutex is zero-initialized and an all-zero
mutex is valid, so the issue only shows up with CONFIG_DEBUG_MUTEXES.

Fixes: b206d9ec19df ("net/mlx5: HWS, register reformat actions with fw")
