[PATCH] ipvs: change type of netns_ipvs->sysctl_sync_qlen_max

[Simon Horman]

From: Zhang Yanfei <zhangyanfei@cn.fujitsu.com>

This member of struct netns_ipvs is calculated from nr_free_buffer_pages
so change its type to unsigned long in case of overflow.  Also, type of
its related proc var sync_qlen_max and the return type of function
sysctl_sync_qlen_max() should be changed to unsigned long, too.

Besides, the type of ipvs_master_sync_state->sync_queue_len should be
changed to unsigned long accordingly.
