Since 'mod_timer()' expects expiration time in jiffies, add
missing 'msecs_to_jiffies()' in 'ath10k_pci_rx_post_pipe()'
and 'ath10k_snoc_rx_post_pipe()'. Also simplify the loops
and fix number of loop iterations in the former (it should
be equal to 'num' (i.e. number of buffers) and not 'num + 1'.

Fixes: 728f95eef523 ("ath10k: rework posting pci rx buffers")
Fixes: a6e149a9ff03 ("ath10k: add hif start/stop methods for wcn3990 snoc layer")
