x86/resctrl: Prefer alloc(sizeof(*foo)) idiom in rdt_init_fs_context()
rdt_init_fs_context() sizes a typed allocation using an explicit
sizeof(type) expression, which checkpatch.pl complains about.
Since this code is about to be factored out and made generic, this
is a good opportunity to fix the code to size the allocation based
on the target pointer instead, to reduce the chance of future mis-
maintenance.
Fix it.
No functional change.
