es1370: Fix debug code

When DEBUG_ES1370 is defined, the compiler shows these warnings:

hw/es1370.c: In function ?es1370_update_voices?:
hw/es1370.c:414: warning: format ?%d? expects type ?int?, but argument 3 has type ?size_t?
hw/es1370.c: In function ?es1370_writel?:
hw/es1370.c:582: warning: format ?%d? expects type ?int?, but argument 3 has type ?long int?
hw/es1370.c:592: warning: format ?%d? expects type ?int?, but argument 3 has type ?long int?
hw/es1370.c:609: warning: format ?%d? expects type ?int?, but argument 3 has type ?long int?
hw/es1370.c: In function ?es1370_readl?:
hw/es1370.c:751: warning: suggest braces around empty body in an ?if? statement

Fix the format strings and add the missing braces.
