[PATCH 14/14] xfree86/os-support: Mark one more variable as unused.

[Cyril Brulebois]

Removing the data_l computing would lead data to be unused in turn, and
a comment confirms it's apparently useless. Keep it anyway just in case,
and only mark the computed length as unused for now.

This warning goes away accordingly:
|   CC     lnx_acpi.lo
| lnx_acpi.c: In function 'lnxACPIGetEventFromOs':
| lnx_acpi.c:81:30: warning: variable 'data_l' set but not used [-Wunused-but-set-variable]
