Wei Chen fdd067ce93 wifi: rtlwifi: fix incorrect error codes in rtl_debugfs_set_write_reg() 
[ Upstream commit 5dbe1f8eb8 ]

If there is a failure during copy_from_user or user-provided data buffer is
invalid, rtl_debugfs_set_write_reg should return negative error code instead
of a positive value count.

Fix this bug by returning correct error code. Moreover, the check of buffer
against null is removed since it will be handled by copy_from_user.

Fixes: 610247f46f ("rtlwifi: Improve debugging by using debugfs")
