iwlwifi: fix possible data overwrite in hcmd callback

Browse source

My commit 3598e1774c
"iwlwifi: fix enqueue hcmd race conditions" move hcmd callback after
command queue reclaim, to avoid call it with hcmd_lock. But since
queue read index was updated, cmd data can be overwritten. Fix problem
by calling callback before taking hcmd_lock and queue reclaim.
