[PATCH] drivers: thermal: intel: tcc_cooling: remove unused variable

[Sumeet Pawnikar <sumeet4linux@gmail.com>]

Remove the unused variable 'ret' in tcc_cooling_init() and simplify the
error handling path. The variable 'ret' was declared but only used to
store the return value of PTR_ERR(tcc_cdev) before immediately returning
it, which is redundant.

Remove the duplicate variable declaration where both 'ret' and 'err' were
declared, but only 'err' was actually needed.
Also, simplify the error path by directly returning PTR_ERR(tcc_cdev)
instead of storing it in an intermediate variable.
