scsi: ufs: fix probe failure masked by crypto engine reset

When ufshcd_host_reset_and_restore() is called, it is possible
that ufshcd_probe_hba() fails and return an error value.
However, the later call to crypto_engine_reset() might succeed
and override the previous error value.
This will result in ufshcd_host_reset_and_restore() returning
success while in fact a serious error may have occured which
should prevent us from continuing in the normal sequence.
Instead, call crypto_engine_reset() only if ufshcd_probe_hba()
was successfull.
