Limit SPI lock/unlock warning msg to debug level.
Existing SPI lock/unlock messages are always prinked. This causes
a headache in prism sysvar package when we need to save the system
variables and SPI lock/unlock are called. Hence, to avoid these
warning messages during sysvar run time, we limit them to debug
level.
