LU-3305 quota: Update SuSE kernel to handle quota changes in 2.4+

This patch address two issues needed for SuSE systems. The first
is 64 bit quotas are not properly support in SLES11 SP1. We update
quota-support-64-bit-quota-format, which is no longer needed for
RHEL system, to allow 64 bit quotas for SP1. The second is the port
of the patch to handle the global lock contention inside the
dqget()/dqput(). We'd avoid calling dqget()/dqput() in
dquot_initialize().
