##### SUMMARY
NVMe devices can have their serial number read by reading (eg) /sys/block/nvme1n1/device/serial, without having to try and run sg_inq, which requires root.

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
Facts collection, linux.py

##### ANSIBLE VERSION
```paste below
$ ansible --version
ansible 2.10.0.dev0
  config file = None
  configured module search path = ['/local/apps/egsadmin/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /local/apps/egsadmin/randy/ansible-src-current/lib/ansible
  executable location = /local/apps/egsadmin/randy/ansible-src-current/bin/ansible
  python version = 3.6.8 (default, Jun 11 2019, 15:15:01) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

```

##### CONFIGURATION
<!--- Paste verbatim output from "ansible-config dump --only-changed" between quotes -->
```paste below
$ ansible-config dump --only-changed
<nothing>
```

##### OS / ENVIRONMENT
<!--- Provide all relevant information below, e.g. target OS versions, network device firmware, etc. -->
AWS NVMe-based systems

##### STEPS TO REPRODUCE
<!--- Describe exactly how to reproduce the problem, using a minimal test-case -->
Run setup task with and without "become" on a system or VM with NVMe and observe that "serial" only appears with "become"

<!--- HINT: You can paste gist.github.com links for larger files -->

##### EXPECTED RESULTS
<!--- Describe what you expected to happen when running the steps above -->
ansible_devices[*].serial is populated for NVMe, regardless of become

##### ACTUAL RESULTS
<!--- Describe what actually happened. If possible run with extra verbosity (-vvvv) -->
ansible_devices[*].serial is populated for NVMe, regardless of become
