[patch 2/2] w1: unlock correct lock on error in w1_seq_show()

[Dan Carpenter]

Smatch complains that we don't unlock "master->mutex" on this error
path.  It looks like it is a typo and we unlock ->bus_mutext where
->mutex was intended.

Fixes: d9411e57dc7f ('w1: Add support for DS28EA00 sequence to w1-therm')
