tty: n_gsm: Debug output allocation must use GFP_ATOMIC
Dan Carpenter <dan.carpenter@oracle.com> reported the following Smatch
warning:
drivers/tty/n_gsm.c:720 gsm_data_kick()
warn: sleeping in atomic context
This is because gsm_control_message() is holding a spin lock so
gsm_hex_dump_bytes() needs to use GFP_ATOMIC instead of GFP_KERNEL.
Fixes: 925ea0fa5277 ("tty: n_gsm: Fix packet data hex dump output")
