Yao Zi 1a1ebc90cd hw/loongarch/virt: Don't abort on access to unimplemented IOCSR 
Since commit f2e61edb29 ("hw/loongarch/virt: Use MemTxAttrs interface
for misc ops") which adds a call to g_assert_not_reached() in the path
of handling unimplemented IOCSRs, QEMU would abort when the guest
accesses unimplemented IOCSRs.

This is too serious since there's nothing fatal happening in QEMU
itself, and the guest could probably continue running if we give zero as
result for these reads, which also matches the behavior observed on
3A5000M real machine.

Replace the assertion with qemu_log_mask(LOG_UNIMP, ...), it's still
possible to examine unimplemented IOCSR access through "-d unimp"
command line arguments.
