Felipe Moura c4c9eab46f sensors/lsm6ds3trc: recover from a failed FIFO drain instead of wedging 
A single failed burst read of FIFO_DATA_OUT was enough to take the board
down.

The drain path gave up on error, unlocked and returned, leaving the FIFO
above its watermark.  INT1 is level triggered on exactly that condition,
so the line stayed asserted, the worker was re-entered the instant the
IRQ was re-enabled, failed again, and that hot loop starved every other
task until the board wedged -- console cut off mid-line, no crash dump.
Observed killing a board within seconds of the first failure.

Fix: if the read fails, empty the FIFO through Bypass and restore the
previous mode bits, which deasserts INT1.  That costs one batch of
samples and acquisition resumes on the next watermark.  Restoring the
saved bits rather than recomputing them preserves the FIFO-only ODR set
by fifo_configure().

Losing a batch is a far better outcome than losing the board.

The underlying cause of these timeouts on esp32s3 was light sleep cutting
the transfer in half; that is fixed separately in esp32s3_i2c.c.  This
commit is the driver recovering gracefully from a failed read whatever
its cause, which it was not before.
