exfat: fix potential wrong error return from get_block
commit 59c30e31425833385e6644ad33151420e37eabe1 upstream.
If there is no error, get_block() should return 0. However, when bh_read()
returns 1, get_block() also returns 1 in the same manner.
Let's set err to 0, if there is no error from bh_read()
