dm integrity: remove set but not used variables 

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

drivers/md/dm-integrity.c: In function 'integrity_metadata':
drivers/md/dm-integrity.c:1557:12: warning:
 variable 'save_metadata_offset' set but not used [-Wunused-but-set-variable]
drivers/md/dm-integrity.c:1556:12: warning:
 variable 'save_metadata_block' set but not used [-Wunused-but-set-variable]

They are never used, so remove it.
