checkpatch: improve quoted string and line continuation test

Browse Source 
Given this patch context,

+#define EFI_ST_DISK_IMG { \
+       0x00000240, "\xbe\x5b\x7c\xac\x22\xc0\x74\x0b" /* .[|.".t. */ \
+       }

the current code misreports a quoted string line continuation defect as
there is a single quote in comment.

The 'raw' line should not be tested for quote count, the comment
substituted line should be instead.
