Mark Rutland 42dbf54e88 arm64: consistently log ESR and page table
When we take a fault we can't handle, we try to dump some relevant
information, but we're not consistent about doing so.

In do_mem_abort(), we log the full ESR, but don't dump a page table
walk. In __do_kernel_fault, we dump an attempted decoding of the ESR
(but not the ESR itself) along with a page table walk.

Let's try to make things more consistent by dumping the full ESR in
mem_abort_decode(), and having do_mem_abort dump a page table walk. The
existing dump of the ESR in do_mem_abort() is rendered redundant, and
removed.
