Interrupt handlers do not have valid process context and hence
current pointer is not valid for software/hardware interrupt
handlers. In WLAN log to user space API current process name is
logged using current->comm but hardware/software interrupts do not
have corresponding current pointer because they use current pointer
of interrupted process. Make changes to not to log process name when
log message is generated from hardware/software interrupt handlers.
