ufs: ti-j721e: Correct error detection
In ti_j721e_ufs_probe there is a call to clk_get_rate but the code after
that attempts to detect an error from that call incorrectly uses
IS_ERR_VALUE. Instead the test should just be for regular error codes.
The call returns an unsigned long so that needs to be cast to a signed type
first of all.
This issue was found by Smatch.
