drm/debugfs: fix plain echo to connector "force" attribute
Using plain echo to set the "force" connector attribute fails with
-EINVAL, because echo appends a newline to the output.
Replace strcmp with sysfs_streq to also accept strings that end with a
newline.
v2: use sysfs_streq instead of stripping trailing whitespace
