rG8cfa6ddcee02: vmm: Fix a resource leak in an error path
Summary

vmmdev_create() increments the VM count as its last step and calls
vmmdev_destroy() if it fails. However, vmmdev_destroy() unconditionally
decrements the count.

Correct this bug by reordering operations.

Fixes: 1092ec8b3375 ("kern: Introduce RLIMIT_VMM")
