mISDN: Fix a sleep-in-atomic bug
[ Upstream commit 93818da5eed63fbc17b64080406ea53b86b23309 ]
The driver may sleep under a read spin lock, and the function call path is:
send_socklist (acquire the lock by read_lock)
skb_copy(GFP_KERNEL) --> may sleep
To fix it, the "GFP_KERNEL" is replaced with "GFP_ATOMIC".
