[PATCH] [POWERPC] Fix return value check logic

[Emil Medve]

debugfs_create_file() return a non-NULL (non-zero) value in case of success

This fixes this non-critical boot-time debuging error message:

[    1.316386] calling  irq_debugfs_init+0x0/0x50
[    1.316399] initcall irq_debugfs_init+0x0/0x50 returned -12 after 0 msecs
[    1.316411] initcall irq_debugfs_init+0x0/0x50 returned with error code -12
