procps-ng : fix pmap uninitialized warnings

pmap.c: In function 'one_proc':
pmap.c:529: warning: 'maxw1' may be used uninitialized in this function
pmap.c:529: warning: 'maxw2' may be used uninitialized in this function
pmap.c:529: warning: 'maxw3' may be used uninitialized in this function
pmap.c:529: warning: 'maxw4' may be used uninitialized in this function
pmap.c:529: warning: 'maxw5' may be used uninitialized in this function

Without -d and -x option, that should be doable to trigger the issue but I haven't found how
