[Xen-devel] [PATCH v2 4/5] xl: improve return and exit codes of cpupool related functions

[Harmandeep Kaur <write.harmandeep@xxxxxxxxx>]

turning  cpupools related functions xl exit codes towards using the
EXIT_[SUCCESS|FAILURE] macros, instead of instead of arbitrary numbers
or libxl return codes.
