Some versions of pHyp will perform the adjunct partition test before the
ANDCOND test. The result of this is that H_RESOURCE can be returned and
cause the BUG_ON condition to occur. The HPTE is not removed. So add a
check for H_RESOURCE, it is ok if this HPTE is not removed as
pSeries_lpar_hpte_remove is looking for an HPTE to remove and not a
specific HPTE to remove. So it is ok to just move on to the next slot
and try again.
