Mark Brown 8a44119ca4 arm64/ptrace: Use saved floating point state type to determine SVE layout 
commit b017a0cea6 upstream.

The SVE register sets have two different formats, one of which is a wrapped
version of the standard FPSIMD register set and another with actual SVE
register data. At present we check TIF_SVE to see if full SVE register
state should be provided when reading the SVE regset but if we were in a
syscall we may have saved only floating point registers even though that is
set.

Fix this and simplify the logic by checking and using the format which we
recorded when deciding if we should use FPSIMD or SVE format.

Fixes: 8c845e2731 ("arm64/sve: Leave SVE enabled on syscall if we don't context switch")
