net: encx24j600: Fix invalid logic in reading of MISTAT register
A loop for reading MISTAT register continues while regmap_read() fails
and (mistat & BUSY), but if regmap_read() fails a value of mistat is
undefined.
The patch proposes to check for BUSY flag only when regmap_read()
succeed. Compile test only.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
