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. Bugzilla: https://bugzilla.suse.com/show_bug.cgi?id=1103431Signed-off-by:
