vmxnet3: avoid format strint overflow warning

gcc-7 notices that "-event-%d" could be more than 11 characters long
if we had larger 'vector' numbers:

drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_activate_dev':
drivers/net/vmxnet3/vmxnet3_drv.c:2095:40: error: 'sprintf' may write a terminating nul past the end of the destination [-Werror=format-overflow=]
sprintf(intr->event_msi_vector_name, "%s-event-%d",
                                     ^~~~~~~~~~~~~
drivers/net/vmxnet3/vmxnet3_drv.c:2095:3: note: 'sprintf' output between 9 and 33 bytes into a destination of size 32

The current code is safe, but making the string a little longer
is harmless and lets gcc see that it's ok.
