Subject: [PATCH -next v3] platform/x86/dell-wmi-sysman: Make some symbols static

Fix the following sparse warnings:

./passobj-attributes.c:38:23: warning: symbol 'po_is_pass_set' was not declared. Should it be static?
./passobj-attributes.c:70:23: warning: symbol 'po_current_password' was not declared. Should it be static?
./passobj-attributes.c:99:23: warning: symbol 'po_new_password' was not declared. Should it be static?
./passobj-attributes.c:103:23: warning: symbol 'po_min_pass_length' was not declared. Should it be static?
./passobj-attributes.c:107:23: warning: symbol 'po_max_pass_length' was not declared. Should it be static?
./passobj-attributes.c:116:23: warning: symbol 'po_mechanism' was not declared. Should it be static?
./passobj-attributes.c:129:23: warning: symbol 'po_role' was not declared. Should it be static?

v2:
- put all of them in a way that each occupies only a single line
v3:
- shorten the warning paths
- put the static codes a single line
