ipw2100: Use GFP_KERNEL instead of GFP_ATOMIC in some memory allocation
The call chain is:
ipw2100_pci_init_one (the probe function)
--> ipw2100_queues_allocate
--> ipw2100_tx_allocate
No lock is taken in the between.
So it is safe to use GFP_KERNEL in 'ipw2100_tx_allocate()'.
BTW, 'ipw2100_queues_allocate()' also calls 'ipw2100_msg_allocate()' which
already allocates some memory using GFP_KERNEL.
