net: remove useless pfmemalloc setting
When __alloc_skb() allocates an skb from fast clone cache, setting pfmemalloc on the clone is not needed. Clone will be properly initialized later at skb_clone() time, including pfmemalloc field, as it is included in the headers_start/headers_end section which is fully copied.

could be potentially seconds, and it's best to let the USB subsystem to deal with the timeouts on errors. The earlier attempt for runtime PM was buggy as the pm_runtime_get/put() calls could get unpaired easily as they did not follow the state of the chan_busy array as described in commit 098de42ad670 ("dmaengine: cppi41: Fix unpaired pm runtime when only a USB hub is connected". Let's fix the issue by adding pm_runtime_get() to where a new transfer is added to the chan_busy array, and calls to pm_runtime_put() where chan_busy array entry is cleared. This prevents any autosuspend timeouts from happening while dma transfers are active.
