scsi: fnic: fix format string overflow warning
The MSI interrupt name can require 11 bytes in addition to the device name, for a total of 23 bytes: drivers/scsi/fnic/fnic_isr.c: In function 'fnic_request_intr': drivers/scsi/fnic/fnic_isr.c:192:4: error: '-fcs-rq' directive writing 7 bytes into a region of size between 5 and 16 [-Werror=format-overflow=] "%.11s-fcs-rq", fnic->name); drivers/scsi/fnic/fnic_isr.c:206:3: note: 'sprintf' output between 12 and 23 bytes into a destination of size 16 sprintf(fnic->msix[FNIC_MSIX_ERR_NOTIFY].devname, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "%.11s-err-notify", fnic->name); This extends the buffer to fit any possible value.
