If the WLAN core is still active during initialization, it might cause
the MCU or DMA to hang. This can happen during soft reboot, so disable
the core + clock early to avoid this issue.

mt76 uses __skb_pad() with free_on_error set to true, this is the same
as calling skb_pad().
This patch does not change any functionality, but it makes it easier to
backport this driver in backports, because skb_pad() is also available
in older kernel versions.

The ucode chunk might be relatively large and the allocation with
kmalloc() may fail occasionally.  Since the data isn't DMA-transferred
but by manual loops, we can use vmalloc instead of kmalloc.
For a better performance, though, kvmalloc() would be the best choice
in such a case, so let's replace with it.
