[PATCH] mtd: nand: print source of "uncorrectable error" message

[Tormod Volden]

From: Tormod Volden <debian.tormod at gmail.com>

Add the function name to the error message.

These messages are not very helpful:

[183356.176682] uncorrectable error :
[183356.180273] uncorrectable error :
[183356.184194] uncorrectable error :
[183356.187773] uncorrectable error :
[183356.191280] uncorrectable error :

Not sure if above messages come from this code. I also believe there must be
a better way, advice welcome. Maybe we need to make sure all possible callers
print additional information if -1 is returned.

But this small change should be better than nothing, meanwhile.

Regards,
Tormod
