Subject: [PATCH -next] drm/ast: Remove set but not used variable 'bo'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/ast/ast_fb.c: In function 'astfb_create':
drivers/gpu/drm/ast/ast_fb.c:194:17: warning:
 variable 'bo' set but not used [-Wunused-but-set-variable]

It never used since introduction in commit 312fec1405dd ("drm: Initial KMS
driver for AST (ASpeed Technologies) 2000 series (v2)")
