**What I did**
Change the return code handling such that it does not produce an ERR level syslog in the case that SAI_STATUS_NOT_SUPPORTED is returned. Instead handle it gracefully.

**Why I did it**
Sonic seems to expect queryEnumCapabilitiesSai() to only be sucessful when it returns SAI_STATUS_SUCCESS. However, SAI_STATUS_NOT_SUPPORTED is also a valid return code if the attribute queried is not supported on a platform.

**How I verified it**
Verified that the new LOG messages are printed at NOTICE level rather than ERROR level.
