platform/x86: hp-wmi: Use zero insize parameter only when supported
commit be9d73e64957 ("platform/x86: hp-wmi: Fix 0x05 error code reported by
several WMI calls") and commit 12b19f14a21a ("platform/x86: hp-wmi: Fix
hp_wmi_read_int() reporting error (0x05)") cause ACPI BIOS Error (bug):
Attempt to CreateField of length zero (20211217/dsopcode-133) because of
the ACPI method HWMC, which unconditionally creates a Field of
size (insize*8) bits:
CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN)
In cases where args->insize = 0, the Field size is 0, resulting in
an error.
Fix this by using zero insize only if 0x5 error code is returned
Tested on Omen 15 AMD (2020) board ID: 8786.
Fixes: be9d73e64957 ("platform/x86: hp-wmi: Fix 0x05 error code reported by several WMI calls")
