linux_spi: Use fgets() to read buffer size

Since fread() returns the number of bytes read, this currently will only
check for errors if it returns 0 (i.e. the file was empty). However, it
is possible for fread() to encounter an error after reading a few bytes,
which this doesn't catch. Fix this by using fgets() instead, which will
return NULL if EOF or an error is encountered, and is simpler anyway.
