LoongArch: KVM: Add interrupt checking for AVEC
commit 6fb1867d5a44b0a061cf39d2492d23d314bcb8ce upstream.
There is a newly added macro INT_AVEC with CSR ESTAT register, which is
bit 14 used for LoongArch AVEC support. AVEC interrupt status bit 14 is
supported with macro CSR_ESTAT_IS, so here replace the hard-coded value
0x1fff with macro CSR_ESTAT_IS so that the AVEC interrupt status is also
supported by KVM.
