[PATCH] lib: sbi: sse: fix invalid errors returned for sse_hart_mask/unmask()

[Clément Léger]

When called twice, sse_hart_mask()/sse_hart_unmask() should return
SBI_EALREADY_STOPPED/SBI_EALREADY_STARTED. This was currently inverted.

Fixes: b919daf49582 ("lib: sbi: Add support to mask/unmask SSE events")
