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. This results
in roaming KPI for maximum transition time exceeding the expected
100ms.
So change info/err prints to debug prints in roaming path
to reduce delays in roaming time.

On rekey, the STA resets it’s PN to 0 but, the
AP sends out pending traffic with old PN values
before it resets the PN as well.
This causes traffic to stall and hence, TSC (transmit
sequence counter) should not be set to zero during rekey.
Instead, obtain last PN number for a non-bss peer while
configuring new key and pass the values to hostap.

wlan_vdev_get_bsspeer() return bss peer without taking the ref count
of the peer and thus if peer is deleted after wlan_vdev_get_bsspeer()
returns a valid peer, the caller will have stale entry of the peer.
Stale entry of peer can lead to Assert.
Use wlan_objmgr_vdev_try_get_bsspeer API for stats to get the BSS
peer which increment the refcount if peer is valid. With this the
peer won't be deleted till the caller release the ref count of the
peer.
