mmc: core: duplicated trial with same freq in mmc_rescan_try_freq()
mmc_rescan_try_freq() tries to init two times with the last frequency.
For example, if host->f_min is 400KHz, we see the message below:
mmc1: mmc_rescan_try_freq: trying to init card at 400000 Hz
mmc1: mmc_rescan_try_freq: trying to init card at 400000 Hz
Andy Ross says that he didn't try this code on a board with an f_min
that exactly matches one of the table entries, which explains why the
bug wasn't detected.
