Christophe JAILLET 18a163687e staging: rtl8192u: Do not use GFP_KERNEL in atomic context 
[ Upstream commit acac75bb451fd39344eb54fad6602dfc9482e970 ]

'rtl8192_irq_rx_tasklet()' is a tasklet initialized in
'rtl8192_init_priv_task()'.
>From this function it is possible to allocate some memory with the
GFP_KERNEL flag, which is not allowed in the atomic context of a tasklet.

Use GFP_ATOMIC instead.

The call chain is:
  rtl8192_irq_rx_tasklet            (in r8192U_core.c)
    --> rtl8192_rx_nomal            (in r8192U_core.c)
      --> ieee80211_rx              (in ieee80211/ieee80211_rx.c)
        --> RxReorderIndicatePacket (in ieee80211/ieee80211_rx.c)
