[PATCH V2] EDAC: remove set but not used variable 'ecc_loc'

[yu kuai]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/edac/i5100_edac.c: In function âi5100_read_logâ:
drivers/edac/i5100_edac.c:489:11: warning: variable âecc_locâ
set but not used [-Wunused-but-set-variable]

It is never used, and so can be removed.
