x86/MCE: Remove min interval polling limitation

commit fbdb328c6bae0a7c78d75734a738b66b86dffc96 upstream.

commit b3b7c4795c ("x86/MCE: Serialize sysfs changes") introduced a min
interval limitation when setting the check interval for polled MCEs.
However, the logic is that 0 disables polling for corrected MCEs, see
Documentation/x86/x86_64/machinecheck. The limitation prevents disabling.

Remove this limitation and allow the value 0 to disable polling again.
