Remove low_latency flag setting from nozomi and mxser drivers
commit 4d8d4d251df8eaaa3dae71c8cfa7fbf4510d967d upstream
[ cebbert@redhat.com: backport to 2.6.27 ]
Remove low_latency flag setting from nozomi and mxser drivers
The kernel oopses if this flag is set.
[and neither driver should set it as they call tty_flip_buffer_push from IRQ
paths so have always been buggy]
