x86/resctrl: Initialize a new resource group with default MBA values
Currently, when a new resource group is created, the allocation values
of the MBA resource are not initialized and remain meaningless data.
For example:
mkdir /sys/fs/resctrl/p1
cat /sys/fs/resctrl/p1/schemata
MB:0=100;1=100
echo "MB:0=10;1=20" > /sys/fs/resctrl/p1/schemata
cat /sys/fs/resctrl/p1/schemata
MB:0= 10;1= 20
rmdir /sys/fs/resctrl/p1
mkdir /sys/fs/resctrl/p2
cat /sys/fs/resctrl/p2/schemata
MB:0= 10;1= 20
Therefore, when the new group is created, it is reasonable to initialize
MBA resource with default values.
Initialize the MBA resource and cache resources in separate functions.
[ bp: Add newlines between code blocks for better readability. ]
