platform/x86: hp-wmi: Fix 0x05 error code reported by several WMI calls

Several WMI queries leverage hp_wmi_read_int function to read their
data. hp_wmi_read_int function was corrected in a previous patch.
Now, this function invokes hp_wmi_perform_query with input parameter
of size zero and the output buffer of size 4.

WMI commands calling hp_wmi_perform_query with input buffer size value
of zero are listed below.

HPWMI_DISPLAY_QUERY
HPWMI_HDDTEMP_QUERY
HPWMI_ALS_QUERY
HPWMI_HARDWARE_QUERY
HPWMI_WIRELESS_QUERY
HPWMI_BIOS_QUERY
HPWMI_FEATURE_QUERY
HPWMI_HOTKEY_QUERY
HPWMI_FEATURE2_QUERY
HPWMI_WIRELESS2_QUERY
HPWMI_POSTCODEERROR_QUERY
HPWMI_THERMAL_PROFILE_QUERY
HPWMI_FAN_SPEED_MAX_GET_QUERY

Invoking those WMI commands with an input buffer size greater
than zero will cause error 0x05 to be returned.

All WMI commands executed by the driver were reviewed and changes
were made to ensure the expected input and output buffer size match
the WMI specification.

Changes were validated on a HP ZBook Workstation notebook,
HP EliteBook x360, and HP EliteBook 850 G8.  Additional
validation was included in the test process to ensure no other
commands were incorrectly handled.
