Assertion on spin_unlock_wr_quick

[Antonio Huete Jimenez <ahuete.devel@xxxxxxxxx>]

Hi all,

In spin_unlock_wr_quick() function, gd->gd_spinlocks_wr is always 
decreased, even when its value is equal to 0. This shouldn't happen, and 
if it happens then something may be wrong. In the patch below, I've 
added a KKASSERT() before the decreasing as recommended by corecode.
