Pass a char buffer parameter with name "errmsg" to nmount().

Browse Source 
For filesystems which use vfs_mount_error() to log an error, this
char buffer will be populated with a string error message.
If nmount() fails, in addition to printing out strerror(errno),
print out the "errmsg" populated by vfs_mount_error().
