Fix the exception occuring in RAM table search issue.
The original search_one_table() function code can only processes the search
for the exception occurring in FLASH/ROM, because the exception and fixup
table usually locate in FLASH. If the exception address is also in
FLASH, it will be OK.
If the exception occurs in RAM, after the u-boot relocation, a
relocation offset should be added.
