The latter was the only place that called the first. The two
functions were split when the iwl_pci_probe called iwl_pci_down
upon failure in the probe. Since iwl_pci_probe undoes its work by
itself, there is no need to split between iwl_pci_down, and
iwl_pci_remove.

Juuso optimised the timer to not run all the
time in commit 3393a608c4.
However, after that it will still run once
more even if all frames just expired. Fixing
that also makes the function return value a

Also, while at it, change the return value

The assumption is that during the hw config, transmission was
already stopped by mac80211. Sometimes the AP can be switching
b/w the ht modes due to intolerant or etc where STA is in
the middle of transmission. In such scenario, buffer overflow
was observed at driver side. And also before updating the rate
control, the frames are continued to xmited with older rates.
This patch ensures that the frames are always xmitted with
updated rates and avoid buffer overflow.

The function wiphy_update_regulatory() uses the static variable
last_request and thus needs to be called with reg_mutex held.
This is the case for all users in reg.c, but the function was
exported for use by wiphy_register(), from where it is called
without the lock being held.
Fix this by making wiphy_update_regulatory() private and introducing
regulatory_update() as a wrapper that acquires and holds the lock.
