vhost: return bool from *_access_ok() functions
Currently vhost *_access_ok() functions return int. This is error-prone
because there are two popular conventions:
1. 0 means failure, 1 means success
2. -errno means failure, 0 means success
Although vhost mostly uses #1, it does not do so consistently.
umem_access_ok() uses #2.
This patch changes the return type from int to bool so that false means
failure and true means success. This eliminates a potential source of
errors.
