Global pause and PFC configuration should be mutually exclusive (i.e. only one of them at most can be set). However, once PFC was turned off, driver automatically turned Global pause on. This is a bug. Fix the driver behaviour to turn off PFC/Global once the user turned the other on. This also fixed a weird behaviour that at a current time, the profile had both PFC and global pause configuration turned on, which is Hardware-wise impossible and caused returning false positive indication to query tools. In addition, fix error code when setting global pause or PFC to change metadata only upon successful change. Also, removed useless debug print.
