x86/entry/32: Add missing ASM_CLAC to general_protection entry

Browse Source 
commit 3d51507f29f2153a658df4a0674ec5b592b62085 upstream.

All exception entry points must have ASM_CLAC right at the
beginning. The general_protection entry is missing one.

Fixes: e59d1b0a2419 ("x86-32, smap: Add STAC/CLAC instructions to 32-bit kernel entry")
