libxl: avoid a dereference of a null pointer
Variable 'l_disk' initialized to a null pointer value, control jumps to 'case
VIR_DOMAIN_DISK_DEVICE_DISK and then taking false branch, Within the expansion
of the macro 'libxlError': Field access results in a dereference of a null
pointer (loaded from variable 'l_disk').
* src/libxl/libxl_driver.c: Field access results in a dereference of a null
pointer (loaded from variable 'l_disk')
