[PATCH] thermal: Replace pr_warn() with pr_warn_once() in user_space_bind()

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

Use pr_warn_once() instead of pr_warn() to print the user space
governor deprecation message in user_space_bind() to reduce the
kernel log noise.

Fixes: 0275c9fb0eff ("thermal/core: Make the userspace governor deprecated")
