hdparm: Remove -Werror=format-nonliteral from compiler flags

hdparm's sysfs I/O functions trigger warnings with
-Wformat-nonliteral, but the format strings are checked
by other means.
This has been verified to be harmless in 9.58.

Removing -Werror=format-nonliteral here allows us to use
-Werror=format-nonliteral globally in OPTIMIZE_FOR=security mode
while keeping hdparm building.
