Subject: [PATCH] mesa/glthread: correctly compare thread handles

As mentioned in the manual - comparing pthread_t handles via the C
comparison operator is incorrect and pthread_equal() should be used
instead.

Cc: Timothy Arceri <tarceri@itsqueeze.com>
Fixes: d8d81fbc316 ("mesa: Add infrastructure for a worker thread to process GL commands.")
