i2c-pca: Fix waitforcompletion() return value
commit 6abb930af064fb1cf4177d32e2c7bfb89eee0fe5 upstream.
ret is still -1, if during the polling read_byte() returns at once
with I2C_PCA_CON_SI set. So ret > 0 would lead *_waitforcompletion()
to return 0, in spite of the proper behavior.
The routine was rewritten, so that ret has always a proper value,
before returning.
