[PATCH][next] phy: samsung-ufs: fix check on failed devm_clk_get call for rx1_symbol_clk

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

The check to see if the call to devm_clk_get on rx1_symbol_clk is checking
the wrong variable, this looks like a copy-paste error. Fix this to check
phy->rx1_symbol instead of phy->rx0_symbol.
