Subject: [PATCH] [asan] suppress the static variable leaks (#1085)

* [asan] suppress the static variable leaks

This is to suppress ASAN false positives for static variables.
For example, the ServiceMethodTable::m_slots is sometimes reported as
leaked.

Signed-off-by: Yakiv Huryk <yhuryk@nvidia.com>

* [asan] add missing SWSS_LOG_ENTER()
