hw/arm/virt.c: Remove newline from error_report() string

hw/arm/virt.c: Remove newline from error_report() string

error_report() strings should not include trailing newlines; remove
the newline from the error we print when devices won't fit into the
address space of the CPU.

This commit also fixes the accidental hardcoded tabs that were in
this line, since we have to touch the line anyway.
