staging: unisys: visornic: Replace GFP_ATOMIC with GFP_KERNEL
As per below information
GFP_KERNEL FLAG
This is a normal allocation and might block. This is the flag to use in
process context code when it is safe to sleep.
GFP_ATOMIC FLAG
The allocation is high-priority and does not sleep. This is the flag to
use in interrupt handlers, bottom halves and other situations where you
cannot sleep
And we can take advantage of GFP_KERNEL , as when system is in low
memory chances of getting success is high compared to GFP_ATOMIC.
As visornic_probe is in process context we can use GPF_KERNEL.
