whensun 7774b82e4a lib: sbi: Fix FP state enable in sbi_fp_save ...

sbi_fp_save() currently sets mstatus.VS before executing floating-point
store instructions. VS controls vector state and does not enable
floating-point instructions.

Set mstatus.FS instead, matching sbi_fp_restore(), so floating-point
state can be saved when FS was previously Off.

Fixes: 718e1d194f ("lib: sbi: Add floating-point context save/restore support.")
