arm64/mpam: modify mpam irq register error log 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I71UGQ


CVE: NA

----------------------------------------------------------------

MPAM interrupts are used to report error information and are non-functional interrupts.
The current interrupt number is set to the default value 0.
As a result, the device startup log contains the error indicating that the MPAM interrupt
registration fails, which is sensitive.
Therefore, the log level is changed to alarm.
