platform/x86: intel_ips: remove unnecessary checks in ips_debugfs_init
As Greg KH explained in:
https://lkml.org/lkml/2015/8/15/114
There no need to check the return value of debugfs_create_file() and
debugfs_create_dir().
This also fix static code checker warnings:
drivers/platform/x86/intel_ips.c:1314
ips_debugfs_init() warn: passing zero to 'PTR_ERR'
drivers/platform/x86/intel_ips.c:1328
ips_debugfs_init() warn: passing zero to 'PTR_ERR'
