x86: Clear TS in irq_ts_save() when in an atomic section
The dynamic FPU context allocation changes caused the padlock driver
to generate the below warning. Fix it by masking TS when doing padlock
encryption operations in an atomic section.
This solves:
BUG: sleeping function called from invalid context at mm/slub.c:1602
