Most of the driver enumeration functions take an array and a maximum
number of entries that they are allowed to fill in. Upon success, they
return the number of entries filled in. This allows them to be easily
used to consecutively.
One exception is the xf86MatchDriverFromFiles() function, which doesn't
return a value, so callers have to manually search the array for the
first empty entry.
This commit modifies the xf86MatchDriverFromFiles() to behave the same
way as others, which makes it easier to deal with.
