Both unbalanced enable for irq and enable of suspended irq
print same warning messages, such as:
......
[20220314100142]------------[ cut here ]------------
[20220314100142]WARNING: CPU: 1 PID: 10332 at kernel/irq/manage.c:723 __enable_irq+0x58/0xa4
[20220314100142]Unbalanced enable for IRQ 38
......
It's confusing. Separate the warning messages to make it clear.
No functional changes.
