In roaming path, while processing roam synch indication info/err
prints at the driver adds up latency to the total roaming
transition time and the KPI for maximum transition time exceeds
the expected 100ms. The printk buffer is protected by a global
raw spinlock for readers and writers. This restricts the contexts that
are allowed to access the buffer. So large latencies exists when
printing to kmsg done with QDF trace levels WARN, INFO, ERROR.
Change the redundant/less significant info, error, warn level
prints in roaming path to debug level.
