x86/fpu/xstate: Fix the ARCH_REQ_XCOMP_PERM implementation
ARCH_REQ_XCOMP_PERM is supposed to add the requested feature to the
permission bitmap of thread_group_leader()->fpu. But the code overwrites
the bitmap with the requested feature bit only rather than adding it.
Fix the code to add the requested feature bit to the master bitmask.
Fixes: db8268df0983 ("x86/arch_prctl: Add controls for dynamic XSTATE components")
