ceph-volume: fix regex usage in `set_dmcrypt_no_workqueue`

- Updated the regex pattern to `r'(\d+\.?)+'` to more accurately
  capture version numbers.

- Replaced `re.match` with `re.search` to properly match the cryptsetup
  version in the output.

- `re.match` only checks for a match at the beginning of the string,
   while `re.search` looks for a match anywhere in the string.

This fix ensures that the function correctly retrieves the
cryptsetup version from the output.
