scsi: stex: Fix gcc 13 warnings

Browse Source 
commit 6d074ce231 upstream.

gcc 13 may assign another type to enumeration constants than gcc 12. Split
the large enum at the top of source file stex.c such that the type of the
constants used in time expressions is changed back to the same type chosen
by gcc 12. This patch suppresses compiler warnings like this one:
