hvc_console: Provide (un)locked version for hvc_resize()
Rename the locking free hvc_resize() function to __hvc_resize() and provide an inline function that locks the hvc_struct and calls __hvc_resize(). The rationale for this patch is that virtio_console calls the hvc_resize() function without locking the hvc_struct. So it needs to call the lock itself. According to naming rules, the unlocked version is renamed and prefixed with "__". References to unlocked function calls in hvc back-ends has been updated.
