qcacld-3.0: Increase bus suspend/resume log levels

Bus suspend/resume log messages are logged with info log
level which is by default not logged in kernel log buffer.
Increase bus suspend/resume log level to error such that
this critical log message is logged in kernel message.

Once wlan suspend/resume feature becomes more stable this
log message can be reduced back to info log level.
