wifi: iwlwifi: fw: Fix debugfs command sending

Browse Source 
[ Upstream commit 048449fc666d736a1a17d950fde0b5c5c8fd10cc ]

During debugfs command handling transport function is used directly,
this bypasses the locking used by runtime operation function
and leads to a kernel warning when two commands are
sent in parallel.

Fix it by using runtime operations function when sending
debugfs command.
