[PATCH -next] i5000_edac: remove set but not used variables 'maxdimmperch, maxch, channel_count'

[YueHaibing]

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

drivers/edac/i5000_edac.c: In function 'i5000_get_mc_regs':
drivers/edac/i5000_edac.c:1138:6: warning:
 variable 'maxdimmperch' set but not used [-Wunused-but-set-variable]

drivers/edac/i5000_edac.c:1137:6: warning:
 variable 'maxch' set but not used [-Wunused-but-set-variable]

drivers/edac/i5000_edac.c: In function 'i5000_init_csrows':
drivers/edac/i5000_edac.c:1256:13: warning:
 variable 'channel_count' set but not used [-Wunused-but-set-variable]

It never used since introduction in
commit eb60705ac5a9 ("drivers/edac: new intel 5000 MC driver")
