Laurent Dufour 4ab8a485f7 powerpc/pseries: Remove confusing warning message. 
Since commit 1211ee61b4 ("powerpc/pseries: Read TLB Block Invalidate
Characteristics"), a warning message is displayed when booting a guest
on top of KVM:

  lpar: arch/powerpc/platforms/pseries/lpar.c pseries_lpar_read_hblkrm_characteristics Error calling get-system-parameter (0xfffffffd)

This message is displayed because this hypervisor is not supporting
the H_BLOCK_REMOVE hcall and thus is not exposing the corresponding
feature.

Reading the TLB Block Invalidate Characteristics should not be done if
the feature is not exposed.

Fixes: 1211ee61b4 ("powerpc/pseries: Read TLB Block Invalidate Characteristics")
