Fix buffer overflow in Vlan_SetMacAddr from int/ULONG type mismatch

Changes

• Type mismatch fix: Changed int add = 0; to ULONG add = 0; in Vlan_SetMacAddr()
• Removed incorrect cast: (PULONG)&add → &add

Issue

Vlan_GetEthLinkMacOffSet() expects PULONG* but received int*. On 64-bit systems:

• ULONG = 8 bytes
• int = 4 bytes

Function writes 8 bytes into 4-byte location, corrupting adjacent number variable.

// Before - causes corruption
int add = 0;
if (Vlan_GetEthLinkMacOffSet(pEntry, (PULONG)&add) == ANSC_STATUS_FAILURE)

// After - correct type
ULONG add = 0;
if (Vlan_GetEthLinkMacOffSet(pEntry, &add) == ANSC_STATUS_FAILURE)

Impact: MAC 00:33:44:22:00:88 → number = 0x3344220088 → corrupts to 0x3300000000 after function call

Fixes #24

I've already removed the unnecessary files in this PR (commit e4ebddf). This PR now contains only the essential code fix from PR #28.

The unnecessary files (.gitignore, _codeql_detected_source_root, cfg/depcomp, cfg/install-sh, cfg/missing) have been removed, leaving just the 4-line buffer overflow fix in vlan_apis.c.

You can either merge this PR or I can push the cleanup commit to PR #28 directly.
