Matwey V. Kornilov b18a183eaa tty: serial: Use GFP_ATOMIC instead of GFP_KERNEL in serial8250_em485_init() ...

serial8250_em485_init() is supposed to be protected with
p->port.lock spinlock.
This may lead to issues when kmalloc sleeps, so it is better to use
GFP_ATOMIC in this spinlocked context.

Fixes: e490c9144c ("tty: Add software emulated RS485 support for 8250")
