Input: hideep - fix the uninitialized use in hideep_nvm_unlock()

[ Upstream commit cac7100d4c51c04979dacdfe6c9a5e400d3f0a27 ]

Inside function hideep_nvm_unlock(), variable "unmask_code" could
be uninitialized if hideep_pgm_r_reg() returns error, however, it
is used in the later if statement after an "and" operation, which
is potentially unsafe.
