pmp-check-mysql-status fails if a status variable contains a space

[mcgoldrickm]

To test, run pmp-check-mysql-status against a status variable containing a space:

Variable_name: wsrep_provider_vendor
        Value: Codership Oy `<[email protected]>

-bash-4.2$ /usr/lib64/nagios/plugins/pmp-check-mysql-status -x wsrep_provider_vendor -C '!=' -T str -w Synced
awk: cmd. line:8:             if ( Codership Oy <[email protected]> != 0 ) {
awk: cmd. line:8:                                     ^ syntax error
awk: cmd. line:19:             if ( Codership Oy <[email protected]> != Synced ) {
awk: cmd. line:19:                                     ^ syntax error

fix is to add escaped quotes around ${VAR} in awk sections:

-bash-4.2$ diff -u /usr/lib64/nagios/plugins/pmp-check-mysql-status ./pmp-check-mysql-status
