scsi: acornscsi: fix build error

A cleanup patch introduced a fatal typo from inbalanced curly braces:

drivers/scsi/arm/acornscsi.c: In function 'acornscsi_host_reset':
drivers/scsi/arm/acornscsi.c:2773:1: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement]
drivers/scsi/arm/acornscsi.c:2795:12: error: invalid storage class for function 'acornscsi_show_info'
 static int acornscsi_show_info(struct seq_file *m, struct Scsi_Host *instance)

The same patch incorrectly changed the argument type of the reset
handler, as shown by this warning:

drivers/scsi/arm/acornscsi.c:2888:27: error: initialization of 'int (*)(struct scsi_cmnd *)' from incompatible pointer type 'int (*)(struct Scsi_Host *)' [-Werror=incompatible-pointer-types]
  .eh_host_reset_handler = acornscsi_host_reset,

This removes one the extraneous opening brace and reverts the
argument type change.

[mkp: fixed checkpatch complaint]
