phy: qualcomm: Adjust indentation in read_poll_timeout

Clang warns:

../drivers/phy/qualcomm/phy-qcom-apq8064-sata.c:83:4: warning:
misleading indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
                 usleep_range(DELAY_INTERVAL_US, DELAY_INTERVAL_US + 50);
                 ^
../drivers/phy/qualcomm/phy-qcom-apq8064-sata.c:80:3: note: previous
statement is here
                if (readl_relaxed(addr) & mask)
                ^
1 warning generated.

This warning occurs because there is a space after the tab on this line.
Remove it so that the indentation is consistent with the Linux kernel
coding style and clang no longer warns.
