If the get_physical_address() call fails, the SH4 get_phys_page_debug()
handler returns an uninitialized address. Instead return -1, which
correspond to "no page found" (see cpu_get_phys_page_debug() doc
string).
This fixes a warning emitted when building with CFLAGS=-O3
(using GCC 10.2.1 20201125):
target/sh4/helper.c: In function ‘superh_cpu_get_phys_page_debug’:
target/sh4/helper.c:446:12: warning: ‘physical’ may be used uninitialized in this function [-Wmaybe-uninitialized]
446 | return physical;
