[PATCH -next 2/4] mtd: tests: return -EIO when mtdtest_read() failed to read requested bytes

[Akinobu Mita]

mtdtest_read() returns -EINVAL if the number of bytes actually read
is smaller than the number of bytes requested.  But mtdtest_write()
returns -EIO in the similar error condition and returning -EIO seems
more appropriate than -EINVAL in this case.
