i2c: spacemit: ensure bus release check runs when wait_bus_idle() fails

Browse source

[ Upstream commit 41d6f90ef5 ]

spacemit_i2c_wait_bus_idle() only returns 0 on success or a negative
error code on failure.

Since 'ret' can never be positive, the final 'else' branch was
unreachable, and spacemit_i2c_check_bus_release() was never called.

This commit guarantees we attempt to release the bus whenever waiting for
an idle bus fails.
