[PATCH] media: vidtv: free pmt_secs on allocation failure

[Matheus Alves de Almeida]

The vidtv_psi_pmt_create_sec_for_each_pat_entry() function allocates
a pmt_secs array and populates it. When a vidtv_psi_pmt_table_init()
failure happens during population, the code returns without freeing
the array, causing a memory leak.

Free pmt_secs on vidtv_psi_pmt_table_init() failure cleanup.
