This is a static checker fix. We write some binary settings to the sysfs file. One of the settings is the "->startup_profile". There isn't any checking to make sure it fits into the pyra->profile_settings[] array in the profile_activated() function. I added a check to pyra_sysfs_write_settings() in both places because I wasn't positive that the other callers were correct.

2015-01-06xen-netback: fixing the propagation of the transmit shaper timeoutPalik, Imre
Since e9ce7cb6b107 ("xen-netback: Factor queue-specific data into queue struct"), the transimt shaper timeout is always set to 0. The value the user sets via xenbus is never propagated to the transmit shaper. This patch fixes the issue.
