sbat: Fix two NULL derefs found with "gcc -fanalyzer"

"gcc -fanalyzer" found two NULL pointer checks we're missing in sbat.c:

include/str.h: In function ‘get_sbat_field.part.0’:
sbat.c:20:14: error: dereference of NULL ‘offset’ [CWE-476] [-Werror=analyzer-null-dereference]
   20 |         if (!*offset)

and

include/str.h: In function ‘parse_sbat’:
sbat.c:140:27: error: dereference of NULL ‘current’ [CWE-476] [-Werror=analyzer-null-dereference]
  140 |         } while (entry && *current != '\0');

Both are simple, and this patch fixes them.
